Minimizing ventricular pacing to reduce atrial fibrillation in sinus-node disease.


BACKGROUND Conventional dual-chamber pacing maintains atrioventricular synchrony but results in high percentages of ventricular pacing, which causes ventricular desynchronization and has been linked to an increased risk of atrial fibrillation in patients with sinus-node disease. METHODS We randomly assigned 1065 patients with sinus-node disease, intact… (More)
