Abstract
A programmable dual chamber cardiac pacemaker is provided which provides improved means for responding to sensed high atrial rates. The pacemaker monitors the sensed high atrial rates and determines whether they are physiological or not, and automatically controls the operative atrial refractory period as a function of whether or not the atrial rate is physiological. The pacemaker is permitted to go into a Wenckebach mode of operation only when it is determined that a sensed high atrial rate is physiological, and that under other conditions will automatically go into a block mode of operation.
