Delayed atrioventricular conduction, as reflected in prolongation of the P-R interval, is commonly found and is a non specific finding in acute rheumatic fever (minor manifestation). Prolongation of atrioventricular conduction may lead to second-degree A-V block, while a complete heart block is a rare event with or without Stokes-Adams attacks. In these cases temporary pace-maker may be usefully employed. Another uncommon symptom of acute rheumatic fever is abdominal pain, which occurs in fewer than 5% of patients, and is usually vague and not acute. An unusual case of onset of rheumatic fever characterized by acute complete heart block and acute abdominal pain simulating appendicitis is reported.
房室传导延迟，表现为P-R间期延长，在急性风湿热中很常见，是急性风湿热（次要表现）的非特异性表现。房室传导延迟可能导致二度房室传导阻滞，而完全性心脏传导阻滞则是罕见事件，无论有无斯托克斯-亚当斯发作。在这些情况下，临时起搏器可能会有用。急性风湿热的另一个不常见症状是腹痛，不到5%的患者会出现，通常不明确且不剧烈。本文报告了一例以急性完全性心脏传导阻滞和类似阑尾炎的急性腹痛为特征的风湿热发病罕见病例。
