There is an apparent correlation between the severity and duration of skeletal muscle involvement, cardiac manifestations and the extent of conduction system disease in polymyositis. Cardiac involvement during the course of polymyositis has been recognized as one of the typical features of skeletal muscle myositis. We report a patient with polymyositis in whom bifascicular block, prolonged P-R interval and congestive heart failure appeared three years before any clinical or laboratory evidence of active skeletal muscle myositis. To the best of our knowledge, this is the first report of polymyositis where cardiac manifestations preceded those of skeletal muscle myositis.
在多发性肌炎中，骨骼肌受累的严重程度和持续时间、心脏表现与传导系统疾病的程度之间存在明显的相关性。在多发性肌炎病程中出现的心脏受累已被认为是骨骼肌肌炎的典型特征之一。我们报告了一名患有多发性肌炎的患者，在出现任何活动性骨骼肌肌炎的临床或实验室证据三年前，就出现了双分支阻滞、P-R间期延长和充血性心力衰竭。据我们所知，这是首例心脏表现先于骨骼肌肌炎表现的多发性肌炎报告。
