Abstract

Supraventricular tachycardia is the most common significant arrhythmia in children. If prolonged, it may cause heart failure and progress to cardiogenic shock warranting prompt treatment. The recommended interventions following vagal manoeuvres are intravenous adenosine and in the unstable patient electrical cardioversion. We present an infant with an unstable supraventricular tachycardia that was resistant to electrical cardioversion and recommended doses of adenosine. He reverted to sinus rhythm with a higher dose of adenosine, suggesting that such doses may be required in refractory supraventricular tachycardia.
