RANTZ1 has recently reviewed the problem of myocarditis occurring in infections of all types: bacterial, rickettsial, virus and parasitic. Other authors2 have reported clinical, electrocardiographic and anatomic observations suggesting myocardial dysfunction in a wide variety of infectious illness. Gore,3 in reviewing a large amount of pathologic material, noted a striking incidence of myocardial disease among patients who died from infectious disease. Electrocardiographic studies in this type of illness have not been frequent or extensive.
