Abstract:
A 13-year-old girl had a witnessed loss of consciousness after a scuffle with another student at school and was found in ventricular fibrillation at the time of arrival of emergency medical services personnel. The patient was successfully defibrillated in the field and was transported to the emergency department as a presumed "traumatic arrest". The patient's initial electrocardiogram was remarkable for a prolonged QT interval, and it was discovered that multiple family members had died of cardiac events as young adults. Genetic testing subsequently revealed a mutation in the RYR2 gene, which is implicated in catecholaminergic polymorphic ventricular tachycardia.
