问题                 Scientists Develop Ways of Detecting Heart Attack
    German researchers have come up with a new generation of defibrillators(除颤器)and early-warning software aimed at offering heart patients greater protection from sudden death from cardiac arrest(心脏骤停).
    In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases are caused by disruption to the heart’ s rhythm. Those most at risk are patients who have already suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing life-threatening disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices take on 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 capable of generating a six-channel electrocardiogram(ECG)within the’ body. This integrated system allows early diagnosis of acute blood-flow problems and a pending(潜在的)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 a new computer software that renders the evaluation of ECG data more precise.
    The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. " Many of the current programs only take into account a linear correlation of the data. We are, however, making use of a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system," Hagen Knaf says. "In this way 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 upon 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show that the new software evaluates the data considerably better.
Defibrillators are useful in curing patients constantly under the threat of heart attack.

选项 A、Right
B、Wrong
C、Not mentioned

答案B

解析 题干:除颤器对于治疗长期受心脏病威胁的病人很有用。根据第二段的“Those...useful in diagnosing life—threatening disruptions to heart rhythms and correcting them automatically by intervening within seconds”可知,除颤器被证实在诊断心律中断和在几秒钟内实施自动干涉以调整心律方面是有用的。文中说的是诊断(diagnosing)和调整(correcting)心率,而不是治疗(curing),故题干表述错误。
