ABSTRACT:
A method and apparatus for detecting a sequence of abnormal events in an electrical signal, such as the depolarization signal of the heart, compares a selective signal parameter to a defined threshold, and measures the maximum value of the signal parameter for each event which exceeds the threshold. The characteristic quantity corresponding to the statistical distribution of the respective maximum values for a defined number of most recently, successively occurring events is calculated, with each newly measured maximum value causing the characteristic quality to be updated. The characteristic quality is compared in a comparator to a defined rated value, and a signal indicating the presence of a sequence of abnormal events in the electrical signal is generated if the characteristic quality differs from the rated value by more than a selected amount.
