摘要
A system and method for regulation of pacing signals, and more particularly for regulation of an atrioventricular interval in a cardiac electrotherapy system based on measurement of blood flow velocity profiles. More particularly, a diastolic blood flow filling wave and an atrial blood flow filling wave are determined and a time delay between peaks of the two waves and/or a superimposition velocity of the two waves relative to one another are utilized for the regulation. The regulation preferably occurs by comparing the measured time delay to a desired time delay or desired superimposition velocity, and the result of the comparison is then employed for regulating the pacing, or regulating the atrio-ventricular interval.
