Abstract:
1. A cardiac resynchronization device, comprising: a therapy module for delivering cardiac resynchronization therapy with a selected atrioventricular delay, wherein the cardiac resynchronization therapy includes delivering ventricular pacing upon expiration of a selected atrioventricular delay AVD a sensing module and a timer module capable of sensing and timing a plurality of sensed and paced intrinsic atrioventricular intervals at a plurality of rates, wherein a sensed intrinsic atrioventricular interval is the interval between an atrial sense and a ventricular sense and wherein a paced intrinsic atrioventricular interval is the interval between an atrial pace and a ventricular sense; a controller coupled to the timer module capable of calculating a plurality of AVD a memory module capable of storing the plurality of atrioventricular delay values; wherein the controller is configured to calculate a plurality of different AVD wherein the controller is configured to calculate a plurality of different AVD wherein the controller is configured to automatically select one of the plurality of stored AVD
