The annual incidence of sudden cardiac death in young athletes is approximately 1 in 200,000. The most common causes include hypertrophic cardiomyopathy and arrhythmogenic right ventricular dysplasia/cardiomyopathy. These genetic disorders typically manifest in the second decade of life and have the potential for sudden death as the first symptom. Medical care providers must be aware of these disease entities when evaluating patients with seizures, syncope, and/or palpitations. The purpose of this article is to describe their genetics, clinical presentation, and diagnosis.

UI	MeSH Term	Description	Entries
D002312	Cardiomyopathy, Hypertrophic	A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).

D016757	Death, Sudden, Cardiac	Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.

D019571	Arrhythmogenic Right Ventricular Dysplasia	A congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the RIGHT VENTRICLE wall and loss of myocardial cells. Primary injuries usually are at the free wall of right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
