Abstract:
A method including:detecting a first fiducial point, associated with a first heart depolarization, at a first electrode associated with a first heart chamber; detecting the first fiducial point, associated with the first heart depolarization, at a second electrode associated with the first heart chamber; determining a time of the detection of the fist fiducial point at the first electrode and a time of the detection of the first fiducial point associated with the second electrode; selecting the first electrode if the first fiducial point is detected at the second electrode before the first fiducial point is detected at the first electrode, and selecting the second electrode if the first fiducial point is detected at the first electrode before the first fiducial point is detected at the second electrode; and delivering from the selected electrode a subsequent stimulation for evoking a contraction of the first heart chamber.
