Atrioventricular (AV) block is a delay or an interruption in the transmission of an impulse from atria to ventricles due to an anatomic or a functional impairment in the conduction system. Atrioventricular block may be congenital or acquired. Electrocardiographic screening of asymptomatic school-aged children (median, 12.4 years) in Japan found the prevalence of a third-degree AV block to be 2 per 100,000. We report a case of asymptomatic complete AV block of unknown etiology in a 13-year-old child who did not require pacemaker placement. The importance of recognizing an asymptomatic complete AV block in the pediatric population, the classification and controversies of pacemaker placement, and the complications of pacemaker placement are discussed.
房室传导阻滞是指由于传导系统的解剖或功能损害，导致冲动从心房向心室传导延迟或中断。房室传导阻滞可分为先天性或后天性。对日本无症状学龄儿童（中位年龄12.4岁）进行心电图筛查发现，三度房室传导阻滞的患病率为十万分之二。我们报告一例13岁病因不明的无症状完全性房室传导阻滞患儿，该患儿无需植入起搏器。本文讨论了认识儿科人群无症状完全性房室传导阻滞的重要性、起搏器植入的分类及争议，以及起搏器植入的并发症。
