Early Recognition of Giant Cell Myocarditis in a Patient With Fascicular Ventricular Tachycardia

Consider myocarditis in patients with ventricular tachycardia and high troponins and nonobstructive coronary artery disease. Early recognition and immunosuppressive therapy are critical for management of GCM. Cardiac magnetic resonance and biopsy are essential for diagnosis. Orthotopic heart transplantation should be considered in all cases of GCM owing to the associated high mortality rates.
