ABSTRACT:
A method for automatically determining the existence of retrograde conduction in a pacemaker patient. At a selected ventricular pacing rate, A-senses are detected, and V-pace to A-sense intervals are measured. If the measured intervals are consistent, it is possible that there is retrograde conduction. To confirm that the A-senses were not due to noise, atrial premature beats, etc., subsequent ventricular pacing pulses are generated in a manner that eliminates the possibility of atrial beats being due to retrograde conduction; a series of simultaneous atrial and ventricular pacing pulses are generated. If A-senses consistent with the previously measured intervals are not sensed, retrograde conduction is confirmed.
