Abstract:
Accelerated ventricular rhythm is similar in rate to the original sinus rhythm. Although 19 cases have been reported in healthy neonates without congenital disease, it is seen with some regularity at tertiary care paediatric cardiac centres. Accelerated ventricular rhythm carries good prognosis, but it is frequently misdiagnosed as ventricular tachycardia and is, thus, unnecessarily treated. The present report describes a case of a neonate who was not properly diagnosed after birth and who was inappropriately treated.
