文氏现象可发生于传导系统的任何部位,其中以发生在房室结为最常见,但在窦房连接处、希氏束、束支及其分支、异位起搏点与其周围心肌的连接处和预激综合征患者的旁道内均可发生文氏型传导障碍。发生于束支内的文氏周期是一种罕见的传导障碍现象,至今报道不多。现将我们见到的2例报告分析如下。
Wen’s phenomenon can occur in any part of the conduction system, which occurs in the atrioventricular node is the most common, but at the sinoatrial junction, His bundle, bundle branch and its branches, ectopic pacemaker and its surrounding myocardium Ventricular dysfunction and Wolff-Parkinson’s syndrome may occur within the bypass pathway may be Venturi-type conduction disorder. The Wen’s cycle, occurring within the bundle branch, is a rare phenomenon of conduction disturbances that has not been reported so far. Now we see the two cases of the report as follows.
