Scientists Develop Ways of Detecting Heart Attack

German researchers have come up with a new generation of defibrillators (除顫器) and early-warning software aimed at offering heart patients greater_________(51) from sudden death from cardiac arrest (心臟停搏).

In Germany alone, around 100,000 people die annually_________ (52) a result of cardiac arrest and many of these cases are caused by disruption to the heart's rhythm. Those most at_________ (53) are patients who have already suffered a heart attack, and for years the use of defibrillators has proved useful in _________ (54) life-threatening disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices_________(55) on a range of functions, such as that of pacemaker(起搏器)

Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted defibrillator _________ (56) of generating a six-channel electrocardiogram (ECG,心電圖)within the body. This integrated system allows _________(57) diagnosis of severe blood-flow problems and a pending (即將發生的)heart attack. It will. be implanted in _________(58) for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that_________(59) the evaluation of ECG data more precise.

The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this _________ (60) undergo regular ECGs. "Many of the current programs only take into_________(61) a linear correlation of the data. We are, however, making use of a non-linear process_________(62) reveals the chaotic patterns of heart beats as an open and complex system," Hagen Knaf says. "In this way changes in the heart_________ (63) over time can be monitored and individual variations in patients taken into account." An old study of ECG data, based upon 600 patients who had to compare risks and to show that the new software evaluates the considerably better.

54. A. leading B. causing C. diagnosing D. repeating

55. A. put B. go C. take D. keep

56. A. worthy B. full C. proud D. capable

57. A. final B. differential C. usual D. early

58. A. doctors B. researchers C. patients D. nurses

59. A. carries B. has C. requires D. makes

60. A. reason B. purpose C. treatment D. chance

61. A. account B. trouble C. confusion D. effort

62. A. what B. that C. since D. it

63. A. beats B. failures C. attacks D. shapes

64. A. suffered B. launched C. avoided D. started

65. A. option B. method C. proposal D. data

科學家探索發現心臟病的方法

德國研究者們發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專家已經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學學院的研究者開發了一種新計算機軟件。這種軟件使心電圖數據更加準確。

大部分有風險的患 者不能用內置除顫器，因此必須接受常規的心電圖檢查。“目前的許多計劃只把數據的線形關系考慮在內。但是我們現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據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據。
