Ventricular fibrillation is typically the initial arrhythmia in commotio cordis following precordium impacts that occur within an electrically vulnerable period of the cardiac cycle. Conversely, complete heart block is very rare in this context, and its mechanism and temporal course are poorly understood. The presented case concerns a 12-year-old boy, athletic skier, who developed a transient complete heart block following commotio cordis. The electrocardiographic features, the proposed block level and mechanisms of complete heart block following commotio cordis are discussed.
心室颤动通常是心脏震荡后最初出现的心律失常，心脏震荡发生于心动周期的电易损期内的胸前区撞击之后。相反，在这种情况下完全性心脏传导阻滞非常罕见，其机制和时间进程尚不清楚。本文介绍的病例是一名12岁的男性竞技滑雪运动员，他在心脏震荡后出现了短暂性完全性心脏传导阻滞。文中讨论了心脏震荡后完全性心脏传导阻滞的心电图特征、推测的阻滞部位及机制。
