The aim is to develop and clinical test of the novel computer program for the identification of the prognostic markers for sudden cardiac death. Among them are T-wave alternans, duration and dispersion of the interval QT, heart rate turbulence. Material and methods: 79 pts with cardiomyopathy and life-threatening ventricular arrhythmias and 30 pts without arrhythmias. The methods of the precision digital processing of the ECG signal are used. Results: The significantly higher values of T-wave alternans, QT dispersion and heart rate turbulence in pts with ventricular arrhythmias were obtained (p
