Thirteen patients with polymyositis were investigated for the presence of cardiac disease by clinical examination, chest x-ray, electrocardiogram, and systolic time intervals. 5 patients had evidence of cardiac involvement. Compared with the other 8 patients, their polymyositis was more long-standing, more severe, and had remained active. Electrocardiogram usually showed arrhythmias and conduction disturbances, and 4 of the 5 patients had abnormal systolic time intervals indicating left ventricular dysfunction. Left ventricular involvement in polymyositis is more frequent than previously recognized and systolic time intervals are a simple, noninvasive method of detecting this.
通过临床检查、胸部X光、心电图和收缩期时间间期，对13例多发性肌炎患者进行了心脏疾病检查。5例患者有心脏受累的证据。与其他8例患者相比，他们的多发性肌炎病程更长、更严重，且仍处于活动期。心电图通常显示心律失常和传导障碍，5例患者中有4例收缩期时间间期异常，提示左心室功能障碍。多发性肌炎中左心室受累比以前认识到的更常见，收缩期时间间期是检测这种情况的一种简单、无创的方法。
