80 autopsy cases with the diagnosis of infectious endocarditis were reviewed from the Department of Pathology of the Instituto Nacional de Cardiología. Cases included were those who had history of conduction abnormalities. 5% of cases had conduction abnormality due to infectious endocarditis. In 12% of cases, this was attributed to some other cause independent of IE. Only 2 cases had complete AV block and in one of them (1.25%) there was a ventricular septal lesion. It was concluded that abnormalities are a least frequent complication in the natural history of IE. Generally it is due to the extension of the infectious process in the aortic valve towards the ventricular septum and when present carries a bad prognosis.
对来自国家心脏病学研究所病理学系的80例诊断为感染性心内膜炎的尸检病例进行了回顾。纳入的病例为有传导异常病史者。5%的病例因感染性心内膜炎出现传导异常。12%的病例，这归因于与感染性心内膜炎无关的其他原因。仅有2例出现完全性房室传导阻滞，其中1例（1.25%）存在室间隔病变。得出的结论是，传导异常是感染性心内膜炎自然病程中最少见的并发症。一般是由于主动脉瓣感染过程向室间隔蔓延，一旦出现则预后不良。
