Key result
Ivabradine successfully induced sinus rhythm in a 38-day-old infant with resistant supraventricular tachycardia and potential accessory pathway-related tachycardia.
Why the study?
Ivabradine is safe and effective for junctional ectopic tachycardia in children, and reports suggest utility in ectopic and focal atrial tachycardia, but experience in resistant supraventricular tachycardia with potential accessory pathway involvement was limited.
Does ivabradine induce sinus rhythm in an infant with refractory supraventricular tachycardia?
Case Report (n=1)
Does ivabradine induce sinus rhythm in an infant with refractory supraventricular tachycardia?
This case report suggests ivabradine may be an effective treatment option for inducing sinus rhythm in infants with refractory supraventricular tachycardia.
Hypothesis-generating for ivabradine in refractory neonatal SVT; should not change practice without controlled trials.
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.

Sülü et al. (2025) conducted a case report in Resistant supraventricular tachycardia (n=1). Ivabradine was evaluated on Induction of sinus rhythm. Ivabradine successfully induced sinus rhythm in a 38-day-old infant with resistant supraventricular tachycardia and potential accessory pathway-related tachycardia.
