Abstract
Methods and systems of identifying an electrode or combination of electrodes of a multi-electrode device for pacing include selecting a first electrode or electrode combination as a first candidate; delivering a pacing pulse through the first candidate and determining a measurement based on sensed cardiac electrical activity resulting from the first candidate pacing; selecting a second candidate; delivering a pacing pulse through the second candidate and determining a measurement based on sensed cardiac electrical activity resulting from the second candidate pacing; comparing the measurement for the first and second candidates; and identifying the first or second candidate for pacing based on the comparison. The measurement may be one or more of activation time ΔTact, activation recovery interval (ARI), a fractioned electrogram width, and a standard deviation of a fractioned electrogram feature.
