Y1 - 2021 N1 - T2 - Decision Making in Perioperative Medicine: Clinical Pearls AB - Postoperative atrial fibrillation (POAF) is the most common sustained arrhythmia after cardiac surgeries (valve surgeries more commonly than coronary artery bypass grafts), thoracic surgeries (most commonly pulmonary and esophageal surgery), and non cardiothoracic surgeries. POAF is a supraventricular tachyarrhythmia leading to ineffective atrial contractility that is newly diagnosed in the postoperative setting. Most of the literature on POAF pertains to cardiothoracic surgeries.
