Atrial ectopic beats, chronic systemic inflammation, autonomic system alterations, anatomic adaptation, myocardial injury and illicit drugs seem to be implicated in the increased prevalence of atrial fibrillation in athletes, but clear evidence is lacking. Treatment of the arrhythmia is a challenging issue, as atrial fibrillation may impair athletic performances and deteriorate athletes’ quality of life. This review focuses on the epidemiology, possible pathophysiological mechanisms, and management of atrial fibrillation in athletes. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.
