Scientists Develop Ways of Detecting Heart Attack

German researchers have (51) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (52) 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 (53) by disruption to the heart’s rhythm. Those most at risk are patients who have (54) suffered a heart attack, and for years the use of defibrillators has proved useful in intervening within seconds. These devices (56) 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 (57) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (58) blood-flow problems and a pe
