Patent ID: 8417337

Claim:
A method of pacing, comprising: disposing first and second electrodes in electrical communication with first and second ventricles of a patient's heart, respectively; delivering pacing stimuli to the first and second ventricles at approximately the same time; employing the second electrode to detect depolarizations of the second ventricle following delivery of the pacing stimuli; in the event that a depolarization is detected by the second electrode within a first time interval following delivery of the pacing stimuli declaring capture of the second ventricle; in the event that a depolarization is detected by the second electrode within a second time interval following the first time interval, declaring loss-of-capture (LOC) of the second ventricle; employing the first electrode to detect depolarizations of the first ventricle following delivery of the pacing stimuli; in the event that a depolarization is detected by the first electrode within a third time interval following delivery of the pacing stimuli declaring capture of the first ventricle; and in the event that a depolarization is detected by the first electrode within a fourth time interval following the first time interval, declaring loss-of-capture (LOC) of the second ventricle; and wherein the second and fourth time intervals are the same duration.
