A 14-year-old boy suffering from chronic rheumatic heart disease came to the emergency department with recurrent episodes of presyncope and syncope. He was found to have complete heart block (CHB) and required temporary pacemaker insertion. Further workup revealed that CHB was secondary to acute rheumatic carditis. His atrioventricular (AV) conduction abnormalities recovered in a stepwise fashion over 5 days while he was being treated with corticosteroids, without the need for permanent pacemaker insertion. This case illustrates that acute rheumatic carditis can rarely present with advanced AV conduction block, which may be reversible.
一名患有慢性风湿性心脏病的14岁男孩因反复出现晕厥前症状和晕厥来到急诊科。他被诊断为完全性心脏传导阻滞(CHB),需要插入临时起搏器。进一步检查发现,CHB继发于急性风湿性心肌炎。在接受皮质类固醇治疗的5天内,他的房室(AV)传导异常逐步恢复,无需插入永久性起搏器。该病例表明,急性风湿性心肌炎很少会出现严重的房室传导阻滞,而这种阻滞可能是可逆的。
