Abstract
An active implantable medical device, such as a pacemaker, defibrillator, cardiovertor and/or a multisite device, having an improved detection of late atrial extrasystoles. The device detects atrial events (EvtA); applies a first window forming a relative atrial refractory period (DARRP) for discriminating (filtering) atrial extrasystoles of an early or average prematurity, and reacts to a variation of the sinusal atrial rate by certain control algorithms. It also applies the detected atrial events to a second window (DLE), distinct from the first window and of longer duration, for the discrimination of the atrial extrasystoles having a low prematurity, called late extrasystoles. The duration of the second window is a variable duration, defined as a fraction of the current average atrial interval (AAI). Further, the second window is used to inhibit temporarily any reaction to a variation of the sinusal atrial rate, in the event of detection of an atrial event inside the second window.
