Abstract
A pacemaker for automatically confirming the presence of, and terminating, pacemaker mediated tachycardia (PMT). A number of V-pace to A-sense intervals are measured. If the measured intervals are consistent, it is possible that there is retrograde conduction giving rise to PMT. To confirm that the A-senses were not due to noise, atrial premature beats, etc., several 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. The PMT should have been terminated by the simultaneous atrial and ventricular pacing, but in any event the PVARP may be lengthened to exceed the longest measured V-pace to A-sense interval.
