Commotio cordis is ventricular fibrillation that results from blunt chest trauma and is a life threatening condition; early resuscitation and defibrillation are critical. This may occur during sporting events or from child abuse and most patients are boys who are younger than 16 years. ⋯ Automatic defibrillators at convenient locations near sporting events, combined with improved cardiopulmonary resuscitation education, may improve chances of survival after this rare phenomenon. Transient cardiac conduction abnormalities and arrhythmias have been observed in survivors; therefore, cardiac clearance before resumption of sports is indicated.

ReviewSudden cardiac death in children and adolescents: introduction and overview.
Sudden unexpected cardiac death (SCD) in a child or adolescent is a devastating event with serious impact on the family, the school, and the community. This article reviews the epidemiology of SCD in children and adolescents and includes a discussion of its incidence and etiologies. It also discusses strategies for prevention.

This article outlines the up-to-date understanding of the molecular basis of disorders that cause sudden death. Several arrhythmic disorders that cause sudden death have been well-described at the molecular level, including the long QT syndromes and Brugada syndrome; this article reviews the current scientific knowledge of these diseases. Hypertrophic cardiomyopathy, a myocardial disorder that causes sudden death also has been well-studied. Finally, a disorder in which myocardial abnormalities and rhythm abnormalities coexist, arrhythmogenic right ventricular dysplasia, is described.
