Abstract
An active implantable medical device, in particular a pacemaker, defibrillator and/or cardiovertor of the multisite type, having an improved resynchronized cardiac stimulation capability for the treatment of cardiac insufficiency in which the maximum stimulation frequency Fmax is gradually increased over time, starting from an initial value of F up to a target value of F . Moreover, when the device shortens the atrio-ventricular delay as the instantaneous heart rate increases, the device also compares the instantaneous heart rate with a predetermined threshold, and allows the reduction of the atrio-ventricular delay only when the instantaneous heart rate is below this predetermined threshold, and gradually increases the atrio-ventricular delay as the instantaneous heart rate increases above the threshold.
