A histological investigation of the atrioventricular (AV) conduction system was performed in two young adult dogs with complete AV block. In both cases, infiltration of lymphocytes and plasma cells into the AV node and loss and disappearance of the conduction fibres were observed. Such inflammatory lesions of the AV conduction system were associated with complete AV block. The aetiology of these changes and the cause of its location at the AV node were not elucidated.
对两只患有完全性房室传导阻滞的成年幼犬进行了房室传导系统的组织学研究。在这两个病例中，均观察到淋巴细胞和浆细胞浸润到房室结，以及传导纤维的缺失和消失。房室传导系统的这种炎性病变与完全性房室传导阻滞有关。这些变化的病因及其位于房室结的原因尚未阐明。
