Accelerated ventricular rhythm in children: A review and report of a case with congenital heart disease

We report a child with accelerated ventricular rhythm (AVR) and congenital heart disease. Three children with congenital heart defect associated with AVR were previously reported, but in each AVR occurred only postoperatively . Because our patient's 24-hour electrocardiograph recording showed AVR rat es, and differences between sinus and AVR rates, exceeding published childh ood limits, we reviewed the topic. On the basis of our review, we suggest g uidelines for diagnosing AVR and differentiating it from ventricular tachyc ardia.
