Ivabradine in the treatment of congenital junctional ectopic tachycardia: a case report and review of the literature.

Congenital junctional ectopic tachycardia is a rare arrhythmia that poses significant management challenges. This report presents a case of neonatal-onset congenital junctional ectopic tachycardia treated with cedilanid, amiodarone, and propafenone but persisted in episodes. Sinus rhythm was restored following the initiation of ivabradine therapy. The review of the literature indicates that ivabradine demonstrates efficacy in the treatment of paediatric junctional ectopic tachycardia, particularly in refractory cases, without significant side effects. These findings suggest that ivabradine has broad applications in the treatment of refractory arrhythmias.
