Pacemaker-Detected Atrial Fibrillation in Patients With Pacemakers: Prevalence, Predictors, and Current Use of Oral Anticoagulation

BACKGROUND: Dual-chamber pacemakers frequently document atrial fibrillation (AF) in patients without symptoms. Pacemaker-detected AF is associated with a 2.5-fold increased risk of stroke, although it is not established whether oral anticoagulation reduces this risk. This study sought to determine the prevalence and predictors of pacemaker-detected AF and to document current oral anticoagulant use. METHODS: A retrospective analysis included all …
