The conduction system in 31 patients (average age 43 years) who died suddenly and unexpectedly is analyzed. Seven cases show essential lesions of the conduction tissue, these lesions being the only pathological findings at all in 5 cases. The loss of conducting fibers is severe and fulfills our morphological criteria for av-block (see Part I). Considering these lesions are the only pathologic findings, there is every reason to believe that these patients died of Adams-Stokes attacks. Lack of evidence of a basic disease means that there is idiopathic loss of conducting fibers. The site of the lesion is mainly the branching bundle and the origin of both bundle branches. Fibrosis is never a main feature, and this is why the author is reluctant to characterize the disease simply as bilateral bundle branch fibrosis.
对31例突然意外死亡患者（平均年龄43岁）的传导系统进行了分析。7例显示传导组织存在原发性病变，其中5例这些病变是唯一的病理发现。传导纤维的丧失很严重，符合我们对房室传导阻滞的形态学标准（见第一部分）。鉴于这些病变是唯一的病理发现，完全有理由相信这些患者死于阿-斯综合征发作。缺乏基础疾病的证据意味着存在特发性传导纤维丧失。病变部位主要是分支束以及双侧束支的起始部。纤维化从来都不是主要特征，这就是为什么作者不愿简单地将该疾病描述为双侧束支纤维化的原因。
