with patients paced in DDD mode at 100 beats/min (bpm) and the AV delay programmed to 350 ms. AV conduction was considered intact when there was a sensed ventricular event after every atrial-paced ...

Alternatively, if the PR interval is normal and the QRS duration is prolonged, then it is most likely second-degree AV nodal block type II, and a pacemaker ... AV nodal conduction and could ...

The normal cardiac conduction system delivers ... that any patient with permanent atrial fibrillation undergoing biventricular pacing also have AV nodal ablation performed to eliminate the ...

which signifies first-degree atrioventricular block, has been found to increase the risk of developing atrial fibrillation, the need for a pacemaker, and premature death. This finding indicates ...

When SAV+ is activated, the pacemaker will search for the patient's intrinsic AV conduction time and extend ... adaptation of the postventricular atrial refractory period (AutoPVARP) and rate ...
