Abstract
Procedure to recognize a ventricular cardiac pathological condition in view of an automatic defibrillation and monitor/defibrillator to implement the procedure Procedure to recognize a ventricular cardiac pathological condition characterized in that after an analog preprocessing, the ECG signals are continuously sampled and digitized, then digitally processed by basic periods in such a manner as to periodically measure distinct basic values according to three criteria of zeros Z, of cardiac frequency FC and of arrythmia RR, then to individually allocate to each value a probability weighting according to a weighting scale specific to each criteria, to proceed to sum these basic values to establish an overall probability over a given duration utilized to determine the triggering of a recognition alarm of a cardiac pathological condition. The invention is of particular interest in cardiology in the medical industry.
