Scientists Develop Ways of Detecting Heart AttackGerman researchers have___1___a new generation of defibrillators and earlywarning 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 pa- tients who have___4___suffered a heart attack,and for years the use of defibrillators has proved useful in diagnosing___ 5___ disruptions to heart rhythms and correcting them automat-ically 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.

Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders the evaluation 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 complex system,”Hagen Knaf says,“___ 13___ changes in the heart beats over time can be monitored and indi- vidual 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 compare risks and to show___15___the new software evaluates the data considerably better.13._________A: SimilarlyB: In this mannerC: OtherwiseD: In this way
