An electrocardiographic study of the families of two children with isolated complete right bundle-branch block is presented. Several cases of classical complete right bundle-branch block were disclosed (17/69 and 3/22 respectively) in three generations of the two families. Personal interviews and parish registers showed that the two families were related, being descendants 8 generations back from a glass-blower who has emigrated to Sweden in the eighteenth century. It is concluded that complete right bundle-branch block can be an autosomal, genetic anomaly which is inherited dominantly but with reduced penetrance and/or expressivity.
本文呈现了对两名患有孤立性完全性右束支传导阻滞儿童的家族进行的心电图研究。在这两个家族的三代人中发现了几例典型的完全性右束支传导阻滞病例（分别为17/69和3/22）。通过个人访谈和教区登记簿发现，这两个家族有亲缘关系，是一名18世纪移民到瑞典的吹玻璃工人的八代后裔。研究得出结论，完全性右束支传导阻滞可能是一种常染色体显性遗传异常，具有显性遗传但外显率降低和/或表现度降低的特点。
