Patent attributes
Cardiac pacemaker, having at least one stimulation pulse generator to selectively generate stimulation pulses for delivery to an atrium or to an atrium and a ventricle of a heart in DDD mode, at least one sensing stage adapted to process electrical signals sensed by an atrial and ventricular sensing electrode to detect an atrial or ventricular event and to generate an atrial or ventricular sense signal upon event detection, a control unit connected to the generator and sensing stage and being adapted to trigger the generator in DDD mode, wherein the control unit is adapted to verify proper atrioventricular conduction and to switch from a regular (DDD) mode, wherein scheduled ventricular stimulation pulses having predetermined positive intensity is triggered unless inhibited to a ventricular pulse suppression mode (VPS mode) wherein no ventricular stimulation pulses or ventricular stimulation pulses of sub-threshold intensity are generated as long as proper atrioventricular conduction is verified.
