Voltage mapping and pulmonary vein isolation in master athletes with atrial fibrillation

Master athletes encompass a wide range of exercise enthusiasts. At the extreme, there is an increased risk of atrial fibrillation (AF). Therapies aimed at rate or rhythm control are often limited given unfavorable side effects. Although studies suggest an increase in left atrial (LA) fibrosis in this population, minimal electrophysiologic data exist regarding the LA voltage mapping and the efficacy of AF ablation with pulmonary vein isolation (PVI).
