Abstract
An active implantable medical device, particularly a cardiac pacemaker, defibrillator and/or cardiovertor capable of detecting the spontaneous depolarisation of the myocardium and determining the instant of its occurrence, which device detects the spontaneous depolarisation (10) of the myocardium through processing of a cardiac signal (E), delivers an information (t) of occurrence of a depolarisation and conditionally discriminates, preferably during consecutive limited time intervals ([t-50, t+200]), a unique characteristic of the cardiac signal giving a temporal information (T.sub.1, T.sub.2, T.sub.3) on the instant of occurrence of the depolarisation. The unique characteristic can particularly be a predetermined singularity of the cardiac signal such as an extreme, particularly the extreme negative, of the first derivative (dE/dt) of the cardiac signal.
