Higher atrial pacing may lower AF burden in bradycardia patients; leaves open causal benefit in randomized trials.
Does atrial pacing reduce atrial fibrillation burden in patients with implanted pacemakers for bradycardia?
Atrial pacing with a higher percentage of pacing (≥50%) significantly reduces atrial fibrillation burden in patients with bradycardia and paroxysmal AF.
