Arrhythmias represent one of the most significant long-term complications in patients with congenital heart disease (CHD).With advancements in surgical and medical care, survival into adulthood has improved dramatically, resulting in an increasing population of adults with CHD (ACHD) who are at risk of arrhythmias.These arrhythmias are associated with a variety of pathophysiological mechanisms including surgical scars, chamber enlargement, myocardial fibrosis, and autonomic dysfunction.This review provides a focused overview of the epidemiology, pathophysiology, diagnosis, and management of arrhythmias in CHD patients, with an emphasis on current therapeutic strategies and long-term considerations.
