高二英语阅读训练(20)AWhy does a commuter (月季票乘客) always look as if he had just been through a war﹖Here is a sad story of a commuter.Mr. Green gets up very early every day and eats a quick breakfast.Then he makes his wife drive him to the station.He arrives on time, but his train doesn't.When it finally comes, he squeezes on (挤上车) and finds there are no more seats.He has to stand with his bag between his knees.There is simply no room to put it down.Suddenly a cold wind hits him in the face.The window is broken. He remembers this summer.At that time the same window didn't even open. The conductor makes his way through the crowd and asks for the commuter's ticket.The ticket, of course, is buried deep in the poor man's breast pocket.He digs for it.The conductor waits impatiently.Finally the train reaches the city.The commuter is already worn out.He says to himself.“My God! I feel as if I've just been through a war!”1.If the commuter had got up several minutes late, he _____.A.would have missed the train B.might still have been able to catch the train C.wouldn't be sad D.would have been away from a war2.The underlined sentence in Paragraph 3 means “______”.A.His ticket is deep in mud.B.He loses his ticket.C.He forgets where his ticket is.D.It is hard to take out his ticket.3.What is the best title for the passage﹖A.A Commuter's Sad Story B.The Crowded TrainC.An Uncomfortable Travel D.Worn OutBAs the saying goes, nothing succeeds like success.People like to deal with a successful person.Why﹖You see, there must be a reason why the person has achieved success.And most obviously it is because he is expert (熟练的) at what he is doing.When given a chance, people would rather deal with the best.Naturally, the best way to produce a success image (形象) is to do a lot of work.Your achievement, and the name it leads to will make known to the public how good you really are.People will know this by your completed record or simply by recognizing it upon seeing you in action, just as it becomes quite obvious that a man is a full-time tennis player when you see him play on the tennis court (网球场地).So will it become obvious that you are skilled in your field when people see you do your work﹖But many other image building ways are practical in producing a success image as will be discussed in the following.4.People like to deal with a successful person probably because they ____.A.hope to know the secret of being successful B.don't believe what he has achieved C.are eager to show respect for him D.feel uncertainty whether he is an expert 5.How can we know how good a person is at his work﹖A.By dealing with him.B.By studying how he has achieved success.C.By just looking at him doing something.D.By watching him playing tennis on the tennis court.6.The passage mainly tells us that ____.A.success image may come after success B.people like to deal with a successful personC.there are many image building ways D.success image is built in one's work 7.The passage is taken from a chapter of a book, whose title is likely to be “___”.A.Nothing Succeeds like Success B.Success in Your FieldC.Success Image building Ways D.A Successful PlayerCUnless we spend money to spot and prevent asteroids (小行星) now, one might crash (撞击) into Earth and destroy life as we know it, some scientists say.Asteroids are bigger versions of the meteoroids (流星) that race across the night sky.Most orbit the sun far from Earth and don't threaten us.But there are also thousands of asteroids whose orbits put them on a collision (碰撞) course with Earth.Buy $50 million worth of new telescopes right now.Then spend $10 million a year for the next 25 years to find the position of most of the space rocks.By the time we pick out a fatal (致命的) one, the scientists say, we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear weapons.But the cost wouldn't be cheap.Is it worth it﹖Two things experts consider when judging any risk are. How likely the event is, how bad the consequences (后果) will be if the event happens.Experts think an asteroid big enough to destroy lots of lives might strike Earth once every 500,000 years.Sounds pretty rare—but if one did fall, it would be the end of the world.“If we don't take care of these big asteroids, they'll take care of us.”says one scientist.“It's that simple.”The cure, though, might be worse than the disease.Do we really want fleets of nuclear weapons sitting around on Earth﹖“The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them,”said a New York Times article.8.What does the passage say about asteroids and metoroids﹖A.They are heavenly bodies similar in nature.B.They are heavenly bodies different in composition.C.There are more asteroids than meteoroids.D.Asteroids are more mysterious than meteoroids.9.What do scientists say about the collision of an asteroid with Earth﹖A.It is very unlikely but the danger exists.B.Such a collision might happen once every 25 years.C.It's still too early to say whether such a collision might happen.D.Collisions of asteroids with Earth happen more often than expected.10.What do people think of the suggestion of using nuclear weapons to change the course of asteroids﹖A.It sounds practical but may not solve the problem.B.It may create more problems than it might solve.C.It is a waste of money because a collision of asteroids with Earth is very unlikely.D.Further research should be done before it proves applicable (适用的).11.We can conclude from the passage that ______.A.while pushing asteroids off course nuclear weapons would destroy the world B.asteroids racing across the night sky are likely to hit Earth in the near futureC.the worry about asteroids can be left to future generations since it's unlikely to happen in our timeD.workable solutions still have to be found to prevent a collision of asteroids with EarthDIn earliest times, men considered lightning to be one of the great mysteries of nature.Some ancient people believed that lightning and thunder were the weapons of the gods.In reality lightning is a flow of electricity formed high above the earth.A single flash of lightning 1.6 kilometers long has enough electricity to light one million light bulbs.The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752.In the same year he also built the first Lightning Rod (避雷针).His device protects buildings from being damaged by lightning.Modern science has discovered that one stroke of lightning contains more than 15 million volts.A spark between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.Scientists estimate (估计) that there are about 2,000 million flashes of lightning per year.Lightning hits the Empire, State Building in New York City 30 to 48 times a year.In the United States alone it kills an average of one person every day.The safest place to be in case of an electrical storm is in a closed car.Outside, one should go to low ground and not get under trees.Also, one should stay out of water and away from metal fences.Inside a house, people should avoid open doorways and windows and not touch wires or metal things.With lightning, it's better to be safe than sorry12.Lightning is actually _____.A.weapon B.electricity C.light D.mystery13.People once thought that lightning came from ______.A.scientists B.ground C.lightning rod D.gods14.Benjamin Franklin ______.A.made the first lightning rod B.built the Empire State BuildingC.invented electricity D.prevented lightning from hitting cars15.______is the best place to be in during an electricity storm.A.Swimming pool B.A high place C.Under a tree D.A carEPeople who are selling things usually put out advertisements about their articles in newspapers and magazines, and on radio and television.Advertisements tell us what we can get to buy, and they can help us to get what we want.If you look at the page of classified (分类的) advertisements in a newspaper, you will see many advertisements that give you just useful information about goods.But, since we always have to choose what to buy with our money, every advertiser uses different ways to get us to choose the things he is advertising.How can we judge what to believe, and what not to believe, before we spend our money﹖The answer is by learning to see through the tricks some advertisers use, so that we do not get fooled very easily.First, we have to know people can be persuaded to make a certain choice if someone promises them something they want.We all have certain wishes, needs, feelings and weaknesses as human beings.A person who suggests that a certain need will be satisfied will have us ready to do what he wants us to do, unless we can find out what his aim is.As Samul Johnson, a famous writer, once said, “Promise, large promise, is the soul of an advertisement.”16.The first paragraph tells us that people _____.A.use advertisements to help sell goodsB.enjoy reading articles in newspapers and magazinesC.are tired of classified advertisements in any kind of mediaD.who are buying things always get what they want17.The underlined word “articles”in the first paragraph means “_____”.A.goods to be sold B.pieces of writingC.useful things D.the words “a”,“an”or “the”18.In the second paragraph, the writer advises people _______.A.not to be fooled B.on how to choose goodsC.on how to put out advertisements D.on what to believe 19.Advertisers try every possible way ______.A.to rob people of their money B.to play tricks on peopleC.to help people to judge D.to persuade people to buy his goods 20.According to this passage, one is ready to do what he is told to ____.A.if he knows others' aim B.unless he is quite experienced C.when he is promised something D.because he is a human being

Methods Retrospective analysis of the clinical data ofan acute myocardial infarction case undergoing PCI surgery, and suffering repeated electrical storms and pharynx posterior wall hemorrhage because of nursing error was made. Results The patient had sudden chest tightness for five hours, and was diagnosed with acute inferior myocardial infarction. During the emergency PCI surgery, electrical storms (ventricular fibrillation) occurred repeatedly. After cardio-pulmonary re-suscitation, and electric defibrillation, the patient regained normal heart rhythm and survived. Butin the process of rescue, the patient bit a clinical thermometer in hismouth when unconscious. Subsequently, a large amount of blood flowed into air-way, oropharynx and the stomach tube. The bleeding was found from pharynx posterior wall through emergency endoscope and fiberoptic bronchoscopy examinations. After treatment of protecting the gastric mucosa, acid suppression, and anticoagulant, the patient was discharged with recovery on the 21st day. Since then the patient has been in a stable condition as the follow up showed.

心室电风暴的临床研究进展张栋;陈俊民【摘要】心室电风暴(VES)是由于心电活动紊乱导致恶性心律失常发生的一种死亡率极高的综合征,其主要临床特点有反复发作的恶性心律失常、发作性晕厥、心脏停搏等.由于其发病快、病情重、预后差等原因,越来越引起临床工作者的重视.以往VES的治疗以抗心律失常药物为主,但疗效不佳,病死率高.近些年来随着对射频消融术、植入型心脏转度除颤器、心脏再同步化治疗、交感神经去除术等一些新技术的临床探索,为VES的治疗提供了新的方法和思路.【期刊名称】《医学综述》【年(卷),期】2014(020)007【总页数】3页(P1228-1230)【关键词】心室电风暴;室性心动过速;心室纤颤【作者】张栋;陈俊民【作者单位】延安大学附属医院心血管二病区,陕西延安716000;延安大学附属医院心血管二病区,陕西延安716000【正文语种】中文【中图分类】R541.7心室电风暴(ventricular electrical storm,VES)又称交感风暴,是心电活动的极不稳定导致的恶性心律失常。
2006年《室性心律失常的诊疗和SCD预防指南》首次明确定义:VES为24 h内发生的室性心动过速(室速)和(或)心室纤颤(室颤)≥2次伴有血流动力学障碍,需要电复律和电除颤等紧急治疗的临床综合征[1]。
VES是心源性猝死的重要机制之一,Sesselberg等[2]研究发现,VES患者比无VES的患者死亡风险高7.4倍。
由于VES发病突然、病情严重、病死率较高,预后恶劣,越来越引起临床工作者的重视。
现对近些年关于VES的临床研究进展进行综述如下。
1 VES病因分析VES可发生在各种情况下。
①器质性心脏病,急性冠状动脉综合征、心肌炎、心肌病、瓣膜性心脏病、先天性心脏病等,其中以急性冠状动脉综合征最常见。
②非心源性疾病,包括出血性脑血管病、急性呼吸窘迫征、急性呼吸衰竭、急性重症胰腺炎、急性肾衰竭等,上述疾病可能通过引起自主神经功能紊乱、损伤心肌因子、低氧血症、电解质失衡等诱发VES。

WHO officials in Beijing said Chinese authorities had granted WHO’s request for up to 20 live samples, which will be analyzed in international laboratories to improve understanding of the killer virus. The two sides are working out the logistics, including how to ship the samples and which lab they will go to. The shipment is “significantly larger” than the last one China provided, which consisted of five live viruses from poultry in 2004. WHO enjoyed good cooperation with China’s Ministry of Health, which has shared viruses from human cases, but confronted problems trying to convince the Ministry of Agriculture to share samples. Through negotiations, the two sides worked out an arrangement that will give the scientists due credit and involve them in subsequent research whenever possible. WHO officials expressed the hope that the agreement could open the way for more regular sharing of viruses, which is important to determine the different types of strains of the deadly bird flu virus that exist and how they affect humans differently. China has reported 34 outbreaks among poultry since the beginning of last year and 15 confirmed human cases of bird flu, resulting in 10 deaths.

剑桥真题阅读解析————————————————————————————————作者:————————————————————————————————日期:剑桥雅思8-第三套试题-阅读部分-PASSAGE 1-阅读真题原文部分:READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Striking Back at Lightning With LasersSeldom is the weather more dramatic than when thunderstorms strike. Their electrical fury inflicts death or serious injury on around 500 people each year in the United States alone. As the clouds roll in, a leisurely round of golf can become a terrifying dice with death - out in the open, a lone golfer may be a lightning bolt's most inviting target. And there is damage to property too. Lightning damage costs American power companies more than $100 million a year.But researchers in the United States and Japan are planning to hit back. Already in laboratory trials they have tested strategies for neutralising the power of thunderstorms, and this winter they will brave real storms, equipped with an armoury of lasers that they will be pointing towards the heavens to discharge thunderclouds before lightning can strike.The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical PowerResearch Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States' power grid from lightning strikes. 'We can cause the lightning to strike where we want it to using rockets, ' says Ralph Bernstein, manager of lightning projects at EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.Bad behaviourBut while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1, 200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. 'Lightning is not perfectly well behaved, ' says Bernstein. 'Occasionally, it will take a branch and go someplace it wasn't supposed to go. 'And anyway, who would want to fire streams of rockets in a populated area? 'What goes up must come down, ' points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed by EPRI, to try to use lasers to discharge lightning safely - and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500, 000 invested so far, a promising system is just emerging from the laboratory.The idea began some 20 years ago, when high-powered lasers were revealing their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionisation in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge.To stop the laser itself being struck, it would not be pointed straight at the clouds. Instead it would be directed at a mirror, and from there into the sky. The mirror would be protected by placing lightning conductors close by. Ideally, the cloud-zapper (gun)would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.A stumbling blockHowever, there is still a big stumbling block. The laser is no nifty portable: it's a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.Bernstein says that Diels's system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. 'I cannot say I have money yet, but I'm working on it, ' says Bernstein. He reckons that the forthcoming field tests will be the turning point - and he's hoping for good news. Bernstein predicts 'an avalanche of interest and support' if all goes well. He expects to see cloud-zappers eventually costing 100, 000 each.Other scientists could also benefit. With a lightning 'switch' at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of 'interactive meteorology' - not just forecasting the weather but controlling it. 'If we could discharge clouds, we might affect the weather, ' he says.And perhaps, says Diels, we'll be able to confront some other meteorological menaces. 'We think we could prevent hail by inducing lightning,' he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones that threaten crops. With luck, as the storm clouds gather this winter, laser-toting researchers could, for the first time, strike back.Questions 1-3Choose the correct letter, A, B, C or D.Write the correct letter in boxes 1-3 on your answer sheet.1 The main topic discussed in the text isA the damage caused to US golf courses and golf players by lightning strikes.B the effect of lightning on power supplies in the US and in Japan.C a variety of methods used in trying to control lightning strikes.D a laser technique used in trying to control lightning strikes.2 According to the text, every year lightningA does considerable damage to buildings during thunderstorms.B kills or injures mainly golfers in the United States.C kills or injures around 500 people throughout the world.D damages more than 100 American power companies.3 Researchers at the University of Florida and at the University of New MexicoA receive funds from the same source.B are using the same techniques.C are employed by commercial companies.D are in opposition to each other.Questions 4-6Complete the sentences below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-6 on your answer sheet.4 EPRI receives financial support from………………………….5 The advantage of the technique being developed by Diels is that it can be used……………… .6 The main difficulty associated with using the laser equipment is related to its……………….Questions 7-10Complete the summary using the list of words, A-I, below.Write the correct letter, A-I, in boxes 7-10 on your answer sheet.In this method, a laser is used to create a line of ionisation by removing electrons from 7 ………………………….

[Abstract] Implantable cardioverter-defibrillator(ICD)has been proven to effectively prevent the sudden cardiac death,however,due to the poor prognosis of ICD postoperative ventricular electrical storm(VES),VES has became a tricky problem confronted by the modern medicine.This article based on the analysis of successful treatment of a patient with ICD postoperative VES,emphasizes the importance of Esmolol to treat VES and the combination of anti-arrhythmia medicine,such as Lidocaine,when necessary.[Key words] Esmolol;β-receptor blocker;Lidocaine;Ventricular electrical storm电风暴(ventricular electrical storm,VES)最初于90年代由Kim等[1]提出,2006年ACC/AHA/ESC首次对VES做出明确的定义:24 h内自发≥2次的伴血流动力学不稳定的室性心动过速和(或)心室颤动,间隔窦性心律,通常需要电转复和电除颤紧急治疗的临床症候群[2]。

Lesson 1Question:1. Why did John Koshak decide to stay although he knew the hurricane would be bad?For the following reasons: For one thing, the house was 23 feet above sea level; for another,he was unwilling to abandon his home.2. How did the man prepare for the hurricane? Why was a generator necessary?They filled bathtubs and pails. Besides, they checked out batteries for portable radio and flashlights, and fuel for the lantern. A generator was necessary because John's father wired several light bulbs to it and prepared a connection to the refrigerator.3. What made it impossible for the Koshak to escape?It was impossible for the Koshers to escape both by car and on foot. The car's electrical system had been killed by water. Meanwhile, the water became too deep for them to escape on foot.4. Why did John Koshak feel a crushing guilt?Because he blamed himself for underestimating the power of the hurricane and then endangering the whole family by his wrong decision not to flee safer inland.5. Why did Grandma Koshak ask children to be sing?A: Because she knew how frightened the children were and wanted to boost their spirit.6. What was a hurricane party? What happened to the party gores?A hurricane party was the one that was held by several vacationers to enjoy the spectacle of the hurricane with a clear and broad view in the fancy Richelieu Apartments from where they believed they would be safe. Richelieu Apartments were smashed apart by the hurricane and 26 people perished.7. What did Grandma Koshak mean when she said," We lost practically all our possessions, but the family came through it. When I think of that, I realize we lost nothing important?" She meant that human lives are more important than material possessions.8. How did the community of Gulfport act after Hurricane Camille was over?They managed to make their lives return to normal and began rebuilding their community without any delay.Paraphrase:1. We're elevated 23 feet.Our house is 23 feet above sea level.2. The place has been here since 1915, and no hurricane has ever bothered it.The house was built in 1915 and since then no hurricane has done any damage to it.3. We can batten down and ride it out.We can prepare ourselves for the hurricane and manage to survive it without much damage.4. The generator was doused, and the lights went out.Water got into the generator, and it didn't work. As a result, the lights were put out.5. Everybody out the back door to the cars!Everybody go out though the back door and get into the cars.6. The electrical system had been killed by water.The electrical system in the cars had been destroyed by water.7. John watched the water lap at the steps, and felt a crushing guilt.When John watched the water inch its way up the steps, he felt a strong sense of guilt because he blamed himself for understanding the ferocity of Camille and endangering the whole family by mak ing the wrong decision not flee inland.8. Get us through this mess, will you?Oh, god! Please help us to get through the danger situation.9. She carried on alone for a few bars, then her voice trailed away.She sang a few words alone and then her voice gradually grew dimmer and stopped.10. Janis had just one delayed reaction.Janis didn't show her fear on the spot during the hurricane, but she revealed her emotions caused b y the hurricane several nights after the hurricane by getting up in the middle of the night, going ou tside and crying softly.翻译:1. But, like thousands of others in the coastal communities, John was reluctant to abandon his home unless the family---his wife, Janis, and their seven children, aged 3 to 11--- was clearly endangered. 但是,和沿海地区其他成千上万的人一样,约翰不愿舍弃自己的家园,除非他的家人—自己的家人贾妮斯以及他们的7个孩子,大的11岁,小的才3岁—明显处于危险之中。
REVIEW ARTICLEElectrical Storm in Patients with an Implanted Defibrillator:A Matter of DefinitionCarsten W .Israel,M.D.∗and S.Serge Barold,M.D.,F .A.C.C.,F .E.S.C.†∗From the Department of Medicine,Division of Cardiology,J.W .Goethe University Hospital,Frankfurt,Germany;and †University of South Florida College of Medicine and Tampa General Hospital,Tampa,FloridaThe term “electrical storm”(ES)indicates a state of cardiac electrical instability manifested by several episodes of ventricular tachyarrhythmias (VTs)within a short time.In patients with an im-plantable cardioverter defibrillator (ICD),ES is best defined as 3appropriate VT detections in 24h,treated by antitachycardia pacing,shock or eventually untreated but sustained in a VT monitoring zone.The number of shocks and inappropriate detections are irrelevant for the definition.ES occurs in approximately 25%of ICD patients within 3years,with typically 5–55individual VTs within one storm.Potential triggers can be found in approximately 66%of patients and include new/worsened heart failure,changes in antiarrhythmic medication,context with other illness,psychological stress,diarrhea,and hypokalemia.In most patients,ES consists of monomorphic VT indicating the presence of reentry while ventricular fibrillation indicating acute ischemia is rare.ES seems to have a low immediate mortality (1%)but frequently (50–80%)leads to hospitalization.Long-term prognostic implications of ES are unclear.The key intervention in ES is reduction of the elevated sympathetic tone by beta blockers and frequently benzodiazepines.Amiodarone i.v.has also been successful and azimilide seems promising while class I antiarrhythmic drugs are usually unsuccessful.Substrate mapping and VT ablation may be useful in treatment and prevention of ES.Prevention of ES requires ICD programming systematically avoiding unnecessary shocks (long VT detection,antitachycardia pacing where ever possible)which otherwise can fuel the sympathetic tone and prolong ES.A.N.E.2007;12(4):375–382The term “electrical storm”was introduced in the early 1990s to indicate a state of cardiac electri-cal instability manifested by several episodes of ventricular tachyarrhythmias (VTs)within a rela-tively short time.1This implied a serious mortality risk (80–90%),2,3and a condition requiring inten-sive care,hemodynamic interventions,(multiple)external cardioversions,and frequent resuscitation.Patients with an implantable cardioverter defib-rillator (ICD)are at a particular risk to develop elec-trical storm because they typically have a severely reduced left ventricular function and in the case of ICDs for secondary prevention a history of previous VT.However,the prognosis of electrical storm in ICD patients—where the device quickly terminates VTs—is not clear.The ICD may render electrical storm a rather harmless event or the situation car-Address for reprints:Carsten W.Israel,M.D.,J.W.Goethe

cause (e.g.ischemia,worsening of heart failure)is not treated.Electrical storm in ICD patients may still be as-sociated with increased mortality,either immedi-ately due to intractable VT (sudden death in ICD patients),4or as a predictor of impaired long-term prognosis.In the decade between 1996and 2006,a number of studies have analyzed the incidence and prognos-tic implications of electrical storm in ICD patients (Table 1).Definition of Electrical StormIn patients without an ICD,electrical storm has been defined as the occurrence of “≥2hemodynamically destabilizing VTs in 24hour,”10C

rhythm;vs =versus;VT =ventricular tachyarrhythmia;Ø=no influence on prognosis;↓=reduced prognosis.(Table 1).In contrast,it has also been defined as “≥20VTs in 24hour or ≥4VTs in 1hour ”in a study on antiarrhythmic drugs versus beta-blocker therapy,17as “VT recurring immediately after ter-mination,”10“VT for at least one half of each of 3days ”,13and as “sustained and non-sustained tachy-cardia resulting in total ventricular ectopic beats in 24hour more than total sinus beats.”14In ICD patients,hemodynamic instability is not part of the definition as arrhythmias are usually terminated within seconds before causing hemody-namic compromise.However,a number of terms similar to or slightly different from electrical storm have been used to describe this entity:“Multiple consecutive,appropriate high-energy discharges,”5“arrhythmic storm,”6“VT clusters,”7“electrical in-stability,”8“short-term recurrent VT,”9and “inces-sant VT.”10Most of these characterizations have been defined and used differently.For example,“incessant VT ”has been equated with electrical storm 10,11or used explicitly in terms of “≥three VT episodes separated by less than 5minutes.”12Simi-larly,“VT clusters ”have been defined as electrical storm,15in the setting of “≥3VTs resulting in ICD therapy in a short period of time ”(not further spec-ified),7or “≥3adequate ICD interventions within 2weeks.”16Villacastin et al.defined electrical storm in ICD recipients as “multiple (≥2)consecutive ap-propriate shock therapies for a single VT episode.”5This differs significantly from the current concept of electrical storm and may reflect a high defibril-lation threshold.The definition “≥3shocks for tachyarrhyth-mia ”used in the era of ICDs without stored electrograms is not useful because it included inappropriate shocks for supraventricularA.N.E.r October2007r Vol.12,No.4r Israel,et al.r•Electrical Storm in ICD Patients r377tachyarrhythmia or sensing artifacts.Likewise,the definition“≥3appropriate shocks for VT”usedfor electrical storm does not take into account theinfluence of(improved)device programming andexcludes patients where VTs are terminated byantitachycardia pacing.Today,most workers usethe definition proposed by Credner et al.of“≥3appropriate VT therapies(antitachycardia pacingor shocks)in24hour.”18It may be argued that“≥3VT detections within24hour which result in ICDtherapy(antitachycardia pacing or shocks)or aresustained(>30second)”may be more appropriateto take into account sustained VT in a monitoringzone not followed by therapy.The termination of electrical storm has only beendefined in one study by Greene et al.19in terms of aperiod of≥2weeks without VT recurrence,whichseems long and thus highly arguable.In summary,electrical storm in ICD patients isbest defined as the detection of≥3VTs in24hour.All appropriately detected VTs(treated by ATP,≥1shock or eventually untreated in a VT monitoringzone but sustained,that is>30second accordingto device memory)form part of the definition.The number of shock discharges and inappropri-ate detections are irrelevant for the definition.VTepisodes in electrical storm have to be separate,that is VT after unsuccessful therapy cannot be re-garded as a second episode.In contrast,incessantVT,that is VT starting shortly(after≥1sinus cycleand within5minutes)after a technically success-ful therapy should be included in the definition,representing a serious form of electrical storm.Repetitive VTs in the first week after ICD implan-tation should not be considered as electrical storm(see below).Incidence of ES in Patients with an ICD Given the lack of consensus about the definitionof electrical storm,it is not surprising that its inci-dence has been reported to vary significantly from10%to60%in ICD patients(Table1).By consid-ering only studies that defined electrical storm as ≥2–3VT episodes in24hour,electrical storm was documented in approximately10–25%of ICD pa-tients12,15,16,19,20during follow-up periods of12to36months.In patients with an ICD for primary pre-vention,electrical storm seems to be less frequentthan in those with an ICD for secondary prevention(5%vs28%in).16Table2.Electrical Storm:Time to First Occurrenceand Number of VT Episodes.Time after ICD No.of VT Author Implantation Episodes Credner18133±135days17±17 Exner129.2±11.5months

are not randomly distributed over time7but were clustered in the majority of patients with≥3VT episodes,the interval between VT episodes being less than1hour in78%of the cases.The50th per-centile for the median time between VT detections for individual patients was as short as26minutes.21 In one of the earliest report on electrical storm in ICD patients from1998,the disturbance occurred at a mean of4–5months after device implanta-tion.18More recent reports revealed that electri-cal storm occurs typically2–3years after ICD im-plantation,16,23(Table2),a finding that may re-flect changes of ICD indications and drug treat-ment.Multiple VT episodes early after epicardial or transvenous ICD implantation most probably orig-inate from myocardial irritation.8,22VT episodes in the first week after ICD implantation are therefore not included into the strict definition of electrical storm because their mechanism appears different from electrical storm which typically occurs later ICD implantation.While the definition of electrical storm as≥3VT episodes in24hour may include rather benign ar-rhythmia clusters,the mean number of VT episodes during an electrical storm can be rather high(e.g. 17–19,cf.Table2).Verma et al.reported a number of shocks during an electrical storm of5±5,23but the study by Greene et al.reported a mean num-ber of55VT episodes,defining the end of electrical storm as a VT free interval of at least2weeks.19Triggers of Electrical StormMost investigations failed to reveal any clear cause for the development of electrical storm in the majority of patients.Credner et al.observed378r A.N.E.r October 2007r Vol.12,No.4r Israel,et al.r •Electrical Storm in ICD Patientshypokalemia,acute myocardial infarction,and acute worsening of heart failure as potential trig-gers of electrical storm in 26%of their patients,18Exner et al.found that patients with electrical storm were less likely to have received a revascularization procedure.12Similarly,in the SHIELDS trial a pre-cipitating factor was identified only in 13%of pa-tients.20In contrast,Greene et al.found a potential cause of electrical storm in 71%of patients:New or worsened heart failure in 15%,adjustment of or noncompliance to antiarrhythmic medication in 20%,(post ICD implantation in 13%),excess alco-hol consumption in 8%,context with other illness in 5%,and unusual psychological stress (driver ’s license suspension,long-distance journey,etc.)in10%.19Similarly,B ¨ansch et al.found a poten-tial cause of electrical storm in 65%of patients:Heart failure in 31%,diarrhea or hypokalemia in 20%,fever or psychological stress (before oper-ation,travel)in 4%.15Other potential causes of electrical storm (e.g.,inappropriate shocks,class III proarrhythmia)have not yet been investigated.These disparate data suggest that obvious causes (is-chemia,heart failure,hypokalemia)seem to cause less than 20%of events.Psychological stress may be a an important trigger but requires

mere coincidence,however,remains a matter of interpretation.The impact of sympa-thetic activity on electrical storm is corroborated by findings of a decreased baroreflex sensitivity,18therapeutic effect of beta-blockers in contrast to an-tiarrhythmic drugs,17and a peak incidence during the morning hours.9Electrical storm seems to have a specific electro-physiological substrate in the majority of patients.In a study of patients with dilated cardiomyopa-thy,VT inducibility was an independent significant predictor for the development of electrical storm.15In all likelihood,the interplay between autonomic nervous system and electrophysiological substrate (which may change over time due to tissue scarring,ischemia,and increased left ventricular dimensions in progressive heart failure)determines the occur-rence of electrical storm.Arrhythmias and ICD Therapiesduring Electrical StormThe vast majority of arrhythmic episodes that constitute an electrical storm consist of monomor-phic VT (86–97%,Table 3);polymorphic VT and ventricular fibrillation are unusual causes (1–7%,Table 3).These observations favor the concept ofA.N.E.r October2007r Vol.12,No.4r Israel,et al.r•Electrical Storm in ICD Patients r379monomorphic VT induction as outlined above as a more important cause of electrical storm than acute ischemia which is more likely to induce ventricular fibrillation or polymorphic VT.In this respect,Verma et al found a higher pro-portion of ventricular fibrillation as the cause of electrical storm,most probably because of their in-clusion criteria(at least two shocks).23Differences in the arrhythmic expression may also be related to the type of patient pared to cardiac arrest/ventricular fibrillation,patients with ventric-ular tachycardia as their ICD indication are more likely to develop electrical storm exclusively with monomorphic VT.The interpretation of stored electrograms plays an important role in tachycardia discrimination. Depending on device filters,amplifiers,and com-pression algorithms,electrogram morphology dif-fers between manufacturers.In some cases,it may be difficult to distinguish ventricular tachycardia from fibrillation based on right ventricular bipo-lar electrograms during VT.In the absence of a surface ECG,the type of VT may be classified ac-cording to its organization into type I(highly or-ganized:monomorphic signals,isoelectric baseline, cycle length>200ms),II(intermediate organiza-tion),or III(disorganized:broad or irregular sig-nal morphology,loss of clear isoelectrical baseline, minimal cycle length<200ms,24).Monomorphic reentrant VT would be expected to show type I organization while ventricular fibrillation would most likely appear as type II or III electrograms. The availability of a farfield electrogram(distal coil electrode versus can or similar)may be used as an approximation of the surface ECG and can be valuable to distinguish polymorphic VT/fibrillation from monomorphic VT.In conclusion,electrical storm consists of monomorphic VT in most patients indicating the presence of reentry due to an electrophysiological substrate.The prevalence of ventricular fibrillation is low indicating other triggers such as acute is-chemia.However,the definition of ventricular fib-rillation based on stored bipolar electrograms has not been standardized.Clinical and Prognostic Implicationsof Electrical StormThe mortality rate of ICD patients is uncertain. Sudden death occurs in approximately2%of pa-tients,4but data from device interrogation is avail-able in a minority of cases.Death due to incessant recurrent VT has also been reported.4,15The most important immediate clinical consequence of elec-trical storm,however,is hospitalization that is re-quired in approximately80%of patients(Table3), particularly with shock delivery(100%hospitaliza-tion for>3shocks).15Thus,electrical storm re-duces quality of life and may induce a state of anx-iety that leads to psychological problems.Some studies but not all have found electrical storm predictive of an impaired prognosis.Credner et al.did not observe an increased mortality in pa-tients with electrical storm compared to other ICD patients.18However,this study involved only14 patients with electrical storm,and mean follow-up was limited to13months.Greene et al.observed a slightly higher mortality in patients with electri-cal storm compared to patients with appropriate ICD therapy and patients without appropriate ICD therapy(mortality25%,16%,and7%,respectively) that did not reach statistic significance.19Over a 1-year follow-up period in the SHIELD trial,ICD patients with electrical storm had no higher mor-tality(2.7%)than ICD patients with isolated VTs (4.3%)or without any VT(2.4%).20In contrast,in the AVID trial,Exner et al.found a significantly higher mortality of patients with electrical storm than in the other study patients(relative risk2.4) with the highest mortality risk in the first3months after electrical storm(relative risk5.4).12Of note, only approximately40%of patients in the AVID trial received beta-blockers compared to76%in the study by Credner et al.This may explain the vary-ing incidence(10%vs20%)and different prognos-tic significance in the reports on electrical storm. Looking exclusively at patients with nonischemic cardiomyopathy(representing21%of patients in Credner et al.and20%in Exner et al.)B¨a nsch et al.found a significantly higher mortality/transplan-tation rate during a mean follow-up of3years in pa-tients with a history of electrical storm(54%after 2years)which was even higher if electrical storm was accompanied by cardiac decompensation(88% after2years).15Similarly,Verma et al.found an in-creased mortality in patients with electrical storm compared to control ICD patients23and like other investigators,found the increase in mortality to be due to progression of heart failure,not arrhythmic death.In contrast to the AVID trial,patients died typically later than3months after electrical storm. This raises the question as to whether electrical380r A.N.E.r October2007r Vol.12,No.4r Israel,et al.r•Electrical Storm in ICD Patientsstorm is an“inciter”of mortality in ICD patients, a contributing factor,or rather an innocent by-stander.Multiple shocks can lead to an increase in troponin levels indicating myocardial injury which may lead to acute inflammation and fibrosis.25,26 Recurrent ventricular fibrillation can cause intra-cellular calcium elevation which may contribute to progression of left ventricular dysfunction.27–29 Therefore,electrical storm particularly with mul-tiple shocks and ventricular fibrillation may con-tribute to the progression of heart failure.On the other hand,the prognostic role of monomorphic and particularly slow VT(harbinger of terminal heart failure?)treated successfully but repetitively by antitachycardia pacing is unknown.Electrical storm in patients with an ICD may represent an event entirely different from patients without an ICD because the time to therapy is much shorter and therefore the risk of hemodynamic impairment much smaller,and because most VT episodes are terminated by antitachycardia pacing instead of ex-ternal cardioversion.Treatment and Preventionof Electrical StormThe key intervention in electrical storm is reduction of the elevated sympathetic tone by beta-blockers,17frequently combined with ben-zodiazepines.8,19Treatment with i.v.amiodarone has also been successful18,19and azimilide seems promising,at least in prevention of electri-cal storm20while class I antiarrhythmic drugs are usually unsuccessful15,17,18or only useful in combination with amiodarone if the latter fails.30 Magnesium and potassium may be helpful partic-ularly in patients with prolonged QT intervals or hypokalemia.In some patients,overdrive pacing by increasing the lower rate of the ICD may termi-nate electrical storm,particularly if dual-chamber pacing is available.Heart failure treatment should be intensified carefully,avoiding a significant de-crease of potassium levels from diuretics.Anti-ischemic treatment by revascularization may be useful in some patients but usually requires a sta-ble condition.Radiofrequency ablation holds great promise in the treatment of electrical storm refrac-tory to amiodarone.31,32Two randomized studies (SMS study,VTach study)are currently being con-ducted to assess catheter ablation as prophylaxis for electrical storm in ICD patients with VT.ICD programming is probably a key issue to pre-vent electrical storm.Since sympathetic overreac-tivity is an important trigger,the risk of shock deliv-ery should be minimized.Antitachycardia pacing can successfully terminate a significant percentage of fast VTs.33So-called safety features that apply a shock after a programmable time window(usually 30second)independent from programming of anti-tachycardia pacing should be prolonged(e.g.to2–5 min)or disabled.In most patients,the number of VT cycles necessary for detection can be increased from nominal values(usually20cycles for VT)to al-low spontaneous termination.It remains unknown if treated VTs would have been sustained had VT detection criteria been programmed more stringent (e.g.requiring≥30consecutive cycles).Data from the DEFINITE trial suggest that many VT episodes do not need to be treated.34Similarly,criteria for re-detection can carefully be prolonged to reduce the risk of inappropriate detection of(repetitive)non-sustained VT in many patients.Though there are no data on the incidence of electrical storm as a result of inappropriate shocks,the latter needs to be avoided.Finally,the risk of worsening of heart failure is increased by unnecessary right ventricu-lar pacing in ICD patients35and may therefore be a trigger of electrical storm preventable by appro-priate programming.Conclusion and Open QuestionsThe incidence and prognostic significance of elec-trical storm in ICD patients are not completely clear because different patient populations(pri-mary vs secondary prophylaxis of sudden cardiac death,ischemic versus nonischemic cardiomyopa-thy,monomorphic VT versus other ICD indica-tions),different definitions of electrical storm,and different follow-up durations have been used.It appears in approximately25%of patients,typi-cally somewhat late(6–36month)after ICD im-plantation.Electrical storm seems to have a low immediate mortality(1%)but frequently(50–80%) leads to hospitalization,particularly after repeti-tive shocks.Several issues remain to be investi-gated in treatment,particularly prevention:role of prophylactic antiarrhythmic drug treatment in ICD patients as indicated in three studies with sotalol, amiodarone,and azimilide,20,36,37the use of pro-phylactic catheter ablation,and the role of ICD programming.The latter includes antitachycar-dia pacing instead of shock therapy whereeverA.N.E.r October2007r Vol.12,No.4r Israel,et al.r•Electrical Storm in ICD Patients r381possible,longer detection times to allow sponta-neous VT termination,and potentially atrial(!) overdrive,an underlying hypothesis that failed in the DAVID trial due to a high incidence of unnec-essary right ventricular pacing in the DDDR mode used in the overdrive group.REFERENCES1.Kowey PR.An overview of antiarrhythmic drug manage-ment of electrical storm.Can J Cardiol1996;(12SupplB):3B–8B.2.Bedell
