Patent ID: 7613514

Claim:
A method comprising: sensing and measuring an atrioventricular delay concluded by a sensed ventricular event; sensing and measuring an interatrial delay (IAD) concluded by a sensed atrial event; determining a first atrio-ventricular delay value, AVD 1 , selected to approximately maximize contractility of a ventricle, using the measured atrioventricular delay concluded by the sensed ventricular event; determining a second atrio-ventricular delay value, AVD 2 , selected to approximately maximize stroke volume of the ventricle, using the measured IAD concluded by the sensed atrial event; providing an interface through which a health care provider can enter a first coefficient K 5 to be applied to the first atrio-ventricular delay value and a second coefficient K 6 to be applied to the second atrio-ventricular delay value; and combining the first and second atrio-ventricular delay values to establish a blended atrio-ventricular delay AVD blended =(K 5 *AVD 1 +K 6 *AVD 2 )/(K 5 +K 6 ), wherein the blended atrio-ventricular delay AVD blended is determined using a the measured IAD and the measured atrio ventricular delay.
