Sudden death in children and adolescents

This article focuses on sudden unexpected cardiac death (SCD) in children and adolescents. The authors discuss the epidemiology of SCD in children and adolescents, its incidence and etiologies, and strategies for prevention. Because most of the episodes of SCD or sudden cardiac arrest in children and adolescents occur in asymptomatic individuals unknown to have an underlying abnormality before their "event," the issues in this article primarily focus on this group of individuals.
