scientists develop ways of detecting heart attack

German researchers have___1___a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection1___2____ sudden death from cardiac arrest in germany alone around 100.000 people die annually as a result of cardiac arrest and many of these cases___3____ by disruption to the heart's rhythm. those most at risk are patients who have___4___ suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing___5____disruptions to heart rhythms and correcting them automatically by intervening within seconds. these devices___6____a range of functions, such as that of pacemaker

heart specialists at freiburg's university clinic have now achieved a breakthrough with an implanted defibrillator___7_____of generating a six-channel electrocardiogram (ecg) within the body. this integrated system allows early diagnosis of___8____blood-tlow problems and a pending heart attack. it will be implanted in patients for the first time this year. meanwhile, researchers at the fraunhofer institute for applied mathematics in kaiserslautern have developed new computer software that renders the evaluation of ecg data___9___.

the overwhelming___10 ____of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ecgs.“many of the current programs only____11___into account a linear correlation of the data. we are, however, making use____12__ a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system2." hagen knaf says,“____13___ changes in the heart beats over time can be monitored and individual variations in patients taken into account3.”an old study of ecg data, based____14__600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show____15___the new software evaluates the data considerably better.

词汇：

defibrillator n去纤颤器

overwhelming adj.压倒的

pending adj.追近的，即将发生的' pacemaker n起搏器

cardiac adj.心脏的 linear adj.线(性)的

implant vt植入 arrest n停止

electrocardiogram心电图

render 提出…… correlation n相互关系

disruption n.中断 chaotic adj. 混乱的

注释：

1…and early-warning software aimed at offering heart patients greater protection. ：本句中aimed at是过去分词短语，作前面两个名词的定语，原意是“把目标瞄准……”，此处可译为 “旨在为心脏病人提供更多保护的早期预报软件”。

2 anon-linear process that reveals the chaotic patterns of heart beats as an open and complex system:这里that引导的是process的定语从句。as是介词，open在此可译为“直观的”。本句的意思是：……能够将心脏跳动的混乱模式作为一个直观而又复杂的系统揭示出来的非线性处理方法。

3 and individual variations in patients taken into account:这里在taken之前省略了与上句相同的情态动词和助动河can be。
