In Germany alone around 100000 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

Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted defibrillator
(56) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows
(57) diagnosis of acute blood-flow problems and a pending heart attack. It will be implanted in

The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this

study of ECG data, based upon 600 patients who had
