Abstract:
1. A method of adjusting an operating atrio-ventricular (AV) interval in a cardiac pacing therapy delivery device, comprising: measuring the following temporal cardiac parameters of a subject's heart: a P-wave duration (PWd) value, a sensed intrinsic atrioventrical (PR) interval, a sensed or paced QRS duration (QRSd) value, and a heart rate (HR) for at least one cardiac cycle; calculating an optimized AV interval (AVopt) as a linear function of the sensed PWd value, the sensed PR interval value, the sensed or paced QRSd value, and the HR value; and storing the calculated AV interval as an operating AV interval in a memory structure of a pacing therapy delivery device.
