Left Ventricular‐Based Cardiac Stimulation Post AV Nodal Ablation Evaluation (The PAVE Study)

For patients undergoing AV node ablation for atrial fibrillation, biventricular pacing provides a significant improvement in the 6-minute hallway walk test and ejection fraction compared to right ventricular pacing. These beneficial effects of cardiac resynchronization appear to be greater in patients with impaired systolic function or with symptomatic heart failure.
