Seventeen relatives of patients with Duchenne's muscular dystrophy (Group A) and 6 relatives of patients with adult type of muscular dystrophy (Group B) were studied. Short PR interval on electrocardiogram and abnormal systolic time interval (STI) were consistent findings in 14 of 15 female relatives (93.35%) in group A, while these criteria were lacking in group B. Myopathic pattern (i.e. tachycardia, short PR interval, R/S ratio in V1 greater than 1.5, significant Q wave in V4, V5, V6 on electrocardiogram) was present in two (13.35%) of 15 female relatives from group A. It was absent in group B. Male relatives in both the groups had normal electrocardiogram and normal systolic time interval.
对17名杜氏肌营养不良患者的亲属（A组）和6名成人型肌营养不良患者的亲属（B组）进行了研究。心电图上PR间期缩短和收缩时间间期（STI）异常是A组15名女性亲属中14名（93.35%）的一致发现，而B组则没有这些标准。A组15名女性亲属中有两名（13.35%）出现肌病模式（即心动过速、PR间期缩短、V1导联R/S比值大于1.5、V4、V5、V6导联出现明显Q波）。B组未出现。两组中的男性亲属心电图和收缩时间间期均正常。
