Scientists Develop

共享题干题【2013年真题】（一） 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_________(51) from sudden death from cardiac arrest (心脏停搏). 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,心电图)within the body. This integrated system allows _________(57) diagnosis of severe blood-flow problems and a pending (即将发生的)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 _____(64) a subsequent heart attack, enabled the researchers to compare risks and to show that the new software evaluates the _____ (65)considerably better.
