A method and apparatus for predicting susceptibility to sudden cardiac death (208) involves simultaneously assessing cardiac electrical stability (206), represented by either the beat-to- beat alternation in the T-wave of the patient's ECG or dispersion of the QT interval and the autonomic influence on the heart (204), represented by either the magnitude of heart rate variability in the ECG or by baroreceptor sensitivity.

L'invention concerne un procédé et un appareil pour prévoir la susceptibilité d'un patient à une mort cardiaque subite (208). Ce procédé permet d'évaluer simultanément la stabilité cardiaque électrique (206), représentée par l'alternance de pulsations cardiaques dans l'onde T de l'ECG du patient, ou par la dispersion de l'intervalle Q-T et l'influence autonome sur le coeur (204) correspondant à l'amplitude de la fréquence cardiaque dans l'ECG ou à la sensibilité du barorécepteur.
