We reported a case of polymyositis with ventricular tachycardia. She had been suffering from proximal dominant muscle weakness and palpitation for 11 months. Holter EKG demonstrated 23 beats ventricular tachycardia. The noninvasive cardiac examination (Thalium cardiac scintigraphy, echocardiography, radionuclide ventriculography) demonstrated no abnormal findings. After initiation of steroid therapy, muscle strength and CK improved and ventricular tachycardia disappeared. Ventricular tachycardia is one of the important complications of polymyositis.
我们报告了一例伴有室性心动过速的多发性肌炎病例。她患有近端为主的肌肉无力和心悸11个月。动态心电图显示有23次室性心动过速发作。无创心脏检查（铊心肌闪烁显像、超声心动图、放射性核素心室造影）未发现异常。开始使用类固醇治疗后，肌肉力量和肌酸激酶水平改善，室性心动过速消失。室性心动过速是多发性肌炎的重要并发症之一。
