Metastatic tumors of the heart are often asymptomatic but they may dominate the clinical picture. The location in the interventricular septum can account for conduction disturbances. The authors report a case of esophagus neoplasm with septal metastasis responsible for a complete atrioventricular block. The histologic study of the bundle of His by serial sections showing the destruction of the conduction fibres by malignant elements has not been carried out till now except in some observations. The prognostic of the atrioventricular metastatic block is very poor; the ten months' survival which was observed in the reported case is one of the most extended in literature.
心脏转移性肿瘤通常无症状，但也可能成为主要临床表现。位于室间隔的肿瘤可导致传导障碍。作者报告了一例食管肿瘤伴间隔转移导致完全性房室传导阻滞的病例。迄今为止，除了一些观察报道外，尚未通过连续切片对希氏束进行组织学研究以显示恶性肿瘤对传导纤维的破坏。房室转移性传导阻滞的预后非常差；该病例观察到的10个月生存期是文献中最长的之一。
