Viral myocarditis is an important entity within the category of infectious cardiomyopathy. Viruses have been implicated in cardiomyopathies as early as the 1950s, when coxsackievirus B was isolated from the myocardium of a newborn baby with a fatal infection. Advances in genetic analysis, such as polymerase chain reaction testing, have aided in the discovery of several viruses that are believed to have roles in viral cardiomyopathies.
