共用题干 Scientists Develop Ways of Detecting Heart AttackGerman 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 pa- tients 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 ( EG G，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 , research- ers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer soft- ware that________(59)the evaluation of EGG data more precise.The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this ________(60)undergo regular EGGs."Many of the current programs only take into________(61)a line-ar correlation of the data. We are,however,making use in 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 ac-count."An old study of EGG 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. _________(51)
