　　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 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 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-flow 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 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 system,” Hagen Knaf says, “ 13 changes in the heart beats over time can be monitored and individual variations in patients taken into account.” 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.

　　科學家探索發(fā)現(xiàn)心臟病的方法

　　德國研究者們發(fā)明了新一代的除顫器和旨在為心臟病人提供更多保護，使他們免遭心臟停止導致的突然死亡的早期預報軟件。

　　僅在德國每年就有10萬人死于心臟停止。其中大部分是由于心律中斷導致的。危險最大的是那些已經(jīng)犯過一次心臟病的病人。幾年來除顫器被證實在控測心律中止和在幾秒中內實施自動干涉以調整心律的診斷中是有用的。這種方法起到了很多作用，例如起博器。

　　弗萊伯大學診所的心臟病老師已經(jīng)在內置除顫器方面取得了突破性成就。這種除顫器可以在體內產(chǎn)生六個頻道的心電圖。這個綜合體系使血液流通總是和即將發(fā)生的心臟病可被早些診斷出來。今年它將第一次被植入病人體內。同時，凱瑟勞特的弗勞胡佛實用數(shù)學學院的研究者開發(fā)了一種新計算機軟件。這種軟件使心電圖數(shù)據(jù)更加準確。

　　大部分有風險的患 者不能用內置除顫器，因此必須接受常規(guī)的心電圖檢查?！澳壳暗脑S多計劃只把數(shù)據(jù)的線形關系考慮在內。但是我們現(xiàn)在使用的是能夠將心臟跳動的混亂模工作為一個直觀而又復雜的系統(tǒng)提示出來的非線性處理方法”。海根?納夫說，“這樣心臟跳動頻率的變化就會受到控制，而病人個人的特征也會得到考慮。”一個基于600位犯心臟病的患者的以前的心電圖數(shù)據(jù)研究使科學家們能夠比較兩種風險，結果顯示新軟件明顯能更好地處理心電圖數(shù)據(jù)。
