ABSTRACT:
A dual-chamber implantable pacemaker automatically sets its AV or PV interval to a value that is a function of the measured natural conduction time, or AR interval, of a user of the pacemaker. The AR interval is determined on a regular basis, thereby permitting the AV or PV interval set by the pacemaker to adaptively change with any changes in the AR interval. The AV or PV interval is set to a value that is a prescribed amount .DELTA. less than or greater than the measured AR interval. The measured AR interval is typically averaged, or otherwise determined or estimated, based on measurements of several cardiac cycles.
