Abstract:
1. A method comprising: detecting intrinsic ventricular activity of a right ventricle; detecting intrinsic ventricular activity of a left ventricle; computing a time difference between the intrinsic ventricular activity of the right ventricle and the intrinsic ventricular activity of the left ventricle; delivering a pacing pulse to one of the right and left ventricles and measuring corresponding intrinsic activity of the other of the right and left ventricles, and computing a second time difference between the pacing pulse and the corresponding intrinsic activity; determining a pacing interval for a v-v delay based at least in part on the time difference between the ventricular activity of the right ventricle and the ventricular activity of the left ventricle, wherein the pacing interval for the v-v delay is set as a function of the time difference between the ventricular activity of the right ventricle and the ventricular activity of the left ventricle and as a function of the second time difference between the pacing pulse and the corresponding intrinsic activity; and delivering one or more pacing pulses to at least one of the right and left ventricles based on the pacing interval.
