Ivabradine treatment for an infant with potential accessory pathway-related refractory supraventricular tachycardia.

Ivabradine has been shown to be safe and effective in treating congenital and postoperative junctional ectopic tachycardia in children; however, in recent years, case reports have suggested that it may also be used to treat automaticity-related ectopic atrial tachycardia and focal atrial tachycardia. Here, we discussed a case in which we used ivabradine to induce sinus rhythm in a 38-day-old baby who had resistant supraventricular tachycardia and investigated potential accessory pathway-related tachycardia.
