Abstract
An active implantable medical device having an automatic DDD/AAI mode switching. This device includes sensing spontaneous atrial and ventricular events, detecting an atrio-ventricular block and stimulating the ventricle and atrium, the ventricular stimulation being applied on the detection of an atrio-ventricular block (AVB ), after completion of a programmed atrio-ventricular delay begun on an atrial event. The device also includes a control algorithm that discriminates a paroxystic AVB from a chronic AVB. In the event of an established chronic AVB, the device stops the automatic mode switching, switches to the DDD mode, and reprograms the atrio-ventricular delay with a shorter value than that which previously existed. The AVB discrimination can be based on, in a first phase, a suspicion of a chronic AVB, and in a second phase, a confirmed presence of a chronic AVB in the event that consecutive suspicions of chronic AVB persist for a predetermined length of time.
