Transient electrocardiographic changes during two episodes of relapsing brucellosis.

Cardiac involvement in the course of acute brucellosis is rare and, when present, is usually manifested by endocarditis. Myocarditis is very infrequent and in the few reported cases, the course of the disease was fulminant. A patient with recurrent brucellosis who presented transient electrocardiographic T wave changes during two episodes of acute illness is reported. It is suggested that the patient had minor asymptomatic myocarditis in the course of recurrent brucellosis.
