• A 19-year-old man presented with fever, migratory polyarthritis, and palpitations; a diagnosis of acute rheumatic fever was made. Twenty-four-hour ambulatory cardiac monitoring (Holter) performed during the patient's hospitalization revealed ventricular tachycardia. Although disturbances in cardiac conduction and rhythm are common during the acute phase of rheumatic fever, malignant ventricular arrhythmias, to our knowledge, have not been described. Recognition of this occurrence emphasizes the need for continuous cardiac monitoring in selected patients.
