Scientists Develop Ways of Detecting Heart Attack【科学家探索发现心脏病的方法】
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 diagnosing __ 5 __ disruption 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-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 com#puter 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 com#plex 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 com#pare risks and to show __ 15 __ the new software evaluates the data considerably better.
