Abstract:
1. A method comprising: detecting a mechanical ventricular event during a cardiac cycle of a heart; determining a timing of the detected mechanical ventricular event during the cardiac cycle; determining a time for delivery of a pre-excitation stimulus to infarct tissue in a ventricle of the heart during a second cardiac cycle based on the timing of the detected mechanical ventricular event; and delivering the pre-excitation stimulus to the infarct tissue at the determined time during the subsequent cardiac cycle; and wherein determining the time for delivery of the pre-excitation stimulus comprises: measuring an A-V determining an A-V interval based upon the A-V wherein delivering the pre-excitation stimulus to the infarct tissue at the determined time comprises: detecting the atrial event during the subsequent cardiac cycle; and delivering the pre-excitation stimulus to the infarct tissue at the A-V interval after the detection; wherein determining the A-V interval based upon the A-V further comprising: evaluating efficacy of the pre-excitation stimulus; and modifying the pre-excitation interval based on the evaluation; and wherein the measured A-V measuring a second A-V comparing the first and second intervals, and wherein modifying the pre-excitation interval based on the evaluation comprises increasing the pre-excitation interval if the first A-V
