Abstract

Atrial fibrillation (AF) is prevalent in cardiac channelopathies and may be the presenting feature in some patients. The pathogenesis is related to the primary ion channel dysfunction in atrial myocytes that affects atrial conduction or repolarization. The development of AF is associated with adverse outcomes, and its management is challenging in these patients. In this article we review the current information on the prevalence, risk factors, pathophysiology, and treatment of AF in specific cardiac channelopathies.
