Abstract:
A dual chamber pacing system adapted for pacing a heart in a patient during a post-implant Time-Adaptive period, comprising:atrial sense means for sensing an atrial signal from an atria of the patient's heart and providing an A-EVENT signal; AV delay timing means for timing an AV delay from an A-EVENT signal; ventricular sense means for sensing a ventricular signal from ventricles of the patient's heart and providing a V-EVENT signal; ventricular pace means for generating and delivering a ventricular pace pulse to the ventricles of the patient's heart at the expiration of the AV delay; means for setting the AV delay at an initial AV delay at a first time related to the time of implant of the dual chamber pacing system in the patient; and means for providing a Time-Adaptive AV delay during a post-implant Time-Adaptive period that gradually changes the initial AV delay to a chronic AV delay at the end of the post-implant Time-Adaptive period, wherein the initial AV delay is a longer time interval than the time interval of the chronic AV delay.
