Does ivabradine improve heart rate control and cardiac function in an infant with junctional ectopic tachycardia?
Ivabradine may be an effective adjunctive therapy for achieving heart rate control and stabilizing cardiac function in infants with refractory junctional ectopic tachycardia.
Ivabradine may aid rate control in refractory infant JET cardiomyopathy; leaves open need for prospective trials before practice change.
An infant with junctional ectopic tachycardia developed tachycardia-induced cardiomyopathy requiring extracorporeal membrane oxygenation for circulatory failure. After oxygenation withdrawal became feasible following intravenous antiarrhythmics, tachycardia recurred with oral transition. Subsequent ivabradine administration resulted in heart rate control and improved cardiac function. We emphasise the role of ivabradine in heart rate control and cardiac function stabilisation in junctional ectopic tachycardia.
