Myocarditis is an inflammatory disease of the myocardium. The clinical presentation of myocarditis may range from subclinical to sudden death. The incidence of fatal myocarditis, which often presents with sudden or rapid death, has been estimated at 0.15/100.000 in the general population and is highest in infants and young adults （but may affect any age group）. However, diffuse myocarditis in autopsies of sudden death is 〈 2% in adult.
