Abstract:
1. A method including: detecting, from one of first and second electrodes, each associated with a first heart chamber, a first fiducial point associated with a first heart depolarization of the first heart chamber; detecting, from the first electrode, a second fiducial point associated with the first heart depolarization; detecting, from the second electrode, a third fiducial point associated with the first heart depolarization; measuring a first time interval between the first and second fiducial points; measuring a second time interval between the first and third fiducial points; selecting the first electrode if the first time interval is longer than the second time interval, and selecting the second electrode if the second time interval is longer than the first time interval; and delivering from the selected electrode a subsequent stimulation for evoking a contraction of the first heart chamber.
