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.
我们报告了一名有包涵体肌炎临床病史且出现单形性室性心动过速的患者。全面评估未发现冠状动脉疾病或心肌病的证据。程序电刺激诱发了患者的临床心动过速以及另一种形态不同的单形性室性心动过速。在植入植入式心律转复除颤器时，对胸大肌进行了活检，证实了包涵体肌炎的诊断。此前尚无包涵体肌炎患者出现室性心动过速的报道。
