Abstract
Background: Atrial remodeling, vagal tone, and atrial ectopic triggers are suggested to contribute to increased incidence of atrial fibrillation (AF) in endurance athletes. How these parameters change with increased lifetime training hours is debated. Hypothesis: Atrial remodeling occurs in proportion to total training history, thus contributing to elevated risk of AF. Methods: We recruited 99 recreational endurance athletes, subsequently grouped according to lifetime training hours, to undergo evaluation of atrial size, autonomic modulation, and atrial ectopy. Athletes were grouped by self-reported lifetime training hours: low (6000 h). Left atrial (LA) volume, left ventricular (LV) dimensi..
