We report the unusual occurrence of complete heart block during attempted right coronary artery cannulation in a patient with pre-existing uncomplicated right bundle branch block (RBBB). This complication occurred due to accidental impingement of the Judkin's right coronary catheter on the left bundle when it transiently slipped across the aortic valve. The block resolved without any complication.
我们报告了1例既往存在单纯性右束支传导阻滞（RBBB）的患者在尝试右冠状动脉插管时发生完全性心脏传导阻滞的罕见情况。这种并发症是由于Judkin's右冠状动脉导管在短暂滑过主动脉瓣时意外撞击左束支所致。传导阻滞自行缓解，未出现任何并发症。
