SYSTEMS AND METHODS FOR MANAGING ATRIAL-VENTRICULAR DELAY ADJUSTMENTS

Abstract: a system and method are provided for managing atrial-ventricular (av) delay adjustments. an av interval is measured that corresponds to an interval between an atrial paced (ap) event or an atrial sensed (as) event and a sensed ventricular (vs) event. a candidate av delay is set based on the av interval and a bundle branch adjustment (bba) value. a qrs characteristic of interest (coi) is measured while utilizing the candidate av delay in connection with delivering a pacing therapy. the bba value is adjusted and the candidate av delay is reset based on the bba value as adjusted. a collection of qrs cois and corresponding candidate av delays are obtained and one of the candidate av delays is selected as a bba av delay. the pacing therapy is managed, based on the bba av delay.
