PROBLEM TO BE SOLVED: To provide an active implantable medical device, such as a pacemaker, defibrillator and/or cardioverter having an AAI and/or an AAI/DDD operating mode.;SOLUTION: This device detects atrial and ventricular events, stimulates the atrium, and calculates an atrial escape interval (AEI). The device defines a critical period preceding or following the AEI and determines, in the event of detection of a ventricular extrasystole (VES), if the moment of occurrence of the VES is in the critical period. The device further recognizes a risk of inappropriate operation and/or false diagnosis related to the temporal proximity of the VES and end of the AEI. In such a case, the device modifies an operating parameter so as to eliminate this risk, for example, by resetting the counting of AEI (AEI*) on detection of the VES. The device can also inhibit a switching of an AAI mode to a DDD mode in the event of risk of the false diagnosis of atrio-ventricular block.;COPYRIGHT: (C)2006,JPO&NCIPI
