Sudden cardiac death in the pediatric and adolescent population

Each year nearly 7,000 children, adolescents, and young adults in the United States as well as tens of thousands worldwide die unexpectedly. Nearly 50% of these deaths occur with little or no warning. This discussion reviews the epidemiology, presentation, diagnosis, and management of sudden cardiac death (SCD). SCD is predominantly due to previously unrecognized structural abnormalities of the heart and underlying or acquired conditions that predispose persons, especially when involved in exercise, to sudden death. Topics considered include SCD presenting signs, symptoms, diagnoses, and when applicable, management of common conditions associated with SCD.
