We report a case of T wave alternans in a patient with HIV cardiomyopathy. T wave alternans is an unusual electrocardiographic finding in acquired long QT syndromes that can precede the development of torsades de pointes. Our patient had multiple risk factors for the development of the acquired long QT syndrome, including HIV cardiomyopathy, electrolyte disturbances, and erythromycin therapy. T wave alternans has not been described previously with HIV cardiomyopathy and only rarely with erythromycin therapy. Patients who have HIV cardiomyopathy and who receive intravenous erythromycin may benefit from monitoring for QT prolongation and electrolyte disturbances to avoid the development of torsades de pointes.
