Abstract:
Atrial fibrillation (AF) is a common complication of cardiovascular surgery. The two most important risk factors for its development are advancing age and a preoperative history of AF. Long-term sequelae, such as a stroke, are uncommon, however, atrial fibrillation frequently results in increased length and cost of hospitalization. Strategies to prevent postoperative AF include perioperative beta-blockers, amiodarone, and atrial pacing. These strategies are most effective in high-risk patients. When AF does occur, treatment includes control of the ventricular rate, systemic anticoagulation, and conversion to sinus rhythm.
