文氏(Wenckbeach)现象常见于房室、窦房传导中。表现为传导时间逐次延长至传导中断的现象。其本质为递减传导。近年来对束支、分支中的文氏现象已引起临床重视,但文氏现象同样可以发生在异位起搏点周围、旁路和折返环路中,常被忽略。本文报道1例折返环路中的文氏现象。
Wenck (Wenckbeach) phenomenon is common in the atrioventricular node, sinoatrial conduction. The performance of conduction time successively extended to the phenomenon of conduction interruption. Its essence is decreasing conduction. In recent years, the bundle branch, the branch of the Wen’s phenomenon has caused clinical attention, but the phenomenon of Venus can also occur around the ectopic pacemaker, bypass and reentry circuits, often overlooked. We report a case of reentrant loop in the Wen’s phenomenon.
