Abstract
An active implantable medical device, especially of the cardiac pacemaker, defibrillator and/or cardiovertor type, and method for the reduction of episodes of arrhythmia, and especially of atrial arrhythmias. The device operates by detecting events of spontaneous electrical activity in a cardiac cavity, especially the atrium; delivering a stimulation to the aforementioned cardiac cavity, which stimulation is controlled according to an actual escape interval such that, at each cardiac cycle, a stimulation is delivered to the cavity if no spontaneous event is detected by the end of a time corresponding to the end of the period of escape interval since the last spontaneous event or the last stimulation in the cavity; counting of the number of successive stimulated events; and discriminating between events detected in the cavity of an extrasystole origin or a non-extrasystole origin. Preferably, the escape interval is modifiable at each cardiac cycle in a manner so as to reduce by a first programmable value the actual escape interval after the detection of a event of spontaneous non extrasystole origin, or to increase by the actual escape interval a second value programmable after delivery of a predetermined number of successive stimulations.
