Upon detection of a ventricular extrasystole, a pacing control algorithm is brought into play to trigger: a stimulation of the atrium, a controlling of the atrium at a faster pacing rate than that of the ventricle during some cycles, a synchronous controlling of the ventricle during a period that is a multiple of a programmed number of cycles, and subsequent to the programmed number of cycles, a slowing of the ventricular rate until either the programmed base rate is reached or a further sinus detection occurs. The algorithm is inactivated on certain conditions, inhibited on certain conditions, and reactivated on further sensed ventricular extrasystoles.
