Sudden cardiac death, primarily sudden arrhythmic death, is a clinical catastrophe that affects unexpectedly many apparently healthy patients as well as patients who have stable cardiovascular disease. It terminates the life of the patient and degrades the quality of life of family and friends. The problem of identifying patients at increased risk for sudden cardiac death is that there is a reciprocal relationship between the risk in different patient subsets and the size of the subset. The size of the subset is an important determinant the number of individuals who will be affected by this unforeseen clinical event. In other words there are many more sudden cardiac deaths among populations at low risk than among those at very high risk. The reason for this is that the size of the population at low risk is much higher than the sizes of populations at high risk (Figure I-1).
