Scientists Develop Ways of Detecting Heart AttackGerman 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(fā)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.
