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 protection 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 hearts 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 intervening within seconds. These devices 6 a range of functions, such as that of pacemaker.
Heart specialists at Freiburgs University Clinic have now achieved a breakthrough with an implanted defibrillator 7 of generating a six-channel electrocardiogram within the body.

Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders of ECG data 9 .

科学家探索发现心脏病的方法
德国研究者们发明了新一代的除颤器和旨在为心脏病人提供更多保护，使他们免遭心脏停止导致的突然死亡的早期预报软件。
仅在德国每年就有10万人死于心脏停止。其中大部分是由于心律中断导致的。危险最大的是那些已经犯过一次心脏病的病人。几年来除颤器被证实在控测心律中止和在几秒中内实施自动干涉以调整心律的诊断中是有用的。这种方法起到了很多作用，例如起博器。
弗莱伯大学诊所的心脏病专家已经在内置除颤器方面取得了突破性成就。这种除颤器可以在体内产生六个频道的心电图。这个综合体系使血液流通总是和即将发生的心脏病可被早些诊断出来。今年它将第一次被植入病人体内。同时，凯瑟劳特的弗劳胡佛实用数学学院的研究者开发了一种新计算机软件。这种软件使心电图数据更加准确。
大部分有风险的患 者不能用内置除颤器，因此必须接受常规的心电图检查。目前的许多计划只把数据的线形关系考虑在内。但是我们现在使用的是能够将心脏跳动的混乱模工作为一个直观而又复杂的系统提示出来的非线性处理方法。海根纳夫说，这样心脏跳动频率的变化就会受到控制，而病人个人的特征也会得到考虑。一个基于 600位犯心脏病的患者的以前的心电图数据研究使科学家们能够比较两种风险，结果显示新软件明显能更好地处理心电图数据。
