Abstract:
We report a patient with a clinical history of inclusion-body myositis presenting with monomorphic ventricular tachycardia. Comprehensive evaluation demonstrated no evidence of coronary artery disease or cardiomyopathy. Programmed electrical stimulation induced the patient's clinical tachycardia as well as a second monomorphic ventricular tachycardia of a different morphology. At the time of implantable cardioverter-defibrillator implant, biopsy of the pectoralis major muscle was performed, which confirmed the diagnosis of inclusion-body myositis. Ventricular tachycardia has not previously been reported in a patient with inclusion-body myositis.
