1 Intermittent loss of capture in a His bundle pacemaker: What is the cause?

4 Figure 3 A: Subthreshold right ventricular support paces during Atrial Capture Management algorithm. B: Enough device-determined “premature ventricular contractions” occur in each episode that the Atrial Capture Management test is aborted. The device returns to “biventricular” pacing, which in this case is His-bundle pacing. ACM = atrial capture management; AP = atrial pacing; AS = atrial sensing; LVP = left ventricular pacing; PVC = premature ventricular contraction; RVP = right ventricular pacing; VS = ventricular sensing.
