摘要: Techniques are provided for estimating optimal atrioventricular pacing delay values use in the ventricles based on features of an intracardiac electrogram (IEGM) signal. Briefly, set upon location atrial repolarization events within IEGM. In one example, end is identified, then interval from depolarization to measured. The by subtracting offset value that so as time delivery V-pulses prior repolarization. this manner, only IEGM signals and hence can be optimal/preferred device itself without requiring surface electrocardiogram (EKG) Doppler echocardiography or other cardiac performance monitoring techniques.
