An autopsied case of Takayasu's arteritis associated with complete atrioventricular (AV) block is described for the first time. The findings of scar formation and diffuse infiltration of lymphocytes into the cardiac conduction system, particularly the AV node, were similar to those in patients with connective tissue diseases or congenital complete heart block. The degree of AV block progressed with aggravation of the disease. These findings suggest that complete AV block may have been induced by acquired autoimmunity involving the cardiac conduction system.
首次描述了一例伴有完全性房室传导阻滞的高安动脉炎尸检病例。瘢痕形成以及淋巴细胞向心脏传导系统，尤其是房室结的弥漫性浸润的表现，与结缔组织疾病或先天性完全性心脏传导阻滞患者的表现相似。房室传导阻滞的程度随着疾病的加重而进展。这些发现表明，完全性房室传导阻滞可能是由涉及心脏传导系统的获得性自身免疫引起的。
