Post‐Operative Atrial Fibrillation Is Influenced by Beta‐Blocker Therapy But Not by Pre‐Operative Atrial Cellular Electrophysiology

Introduction: We investigated whether post‐cardiac surgery (CS) new‐onset atrial fibrillation (AF) is predicted by pre‐CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta‐blocker therapy may involve pre‐CS pharmacological remodeling.
