An infant with junctional ectopic tachycardia treated with a multidrug regimen including ivabradine.

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.
