Abstract:
1. A method of adjusting an operating ventricle-to-ventricle (V-V) interval in a cardiac pacing therapy delivery device, comprising: determining an initial optimized V-V interval; 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, a heart rate (HR) for at least one cardiac cycle; calculating a series of optimized V-V intervals 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 series of optimized V-Vopt as operating V-V intervals in a memory structure of a pacing therapy delivery device.
