文氏现象是传导阻滞的一种特殊形式,它常发生于房室交接处。本例异位起搏点在房室交接处,由于存在逆行阻滞,所以不存在逆行P′波;但发生下行性文氏型(3:2)传出阻滞,表现为R-R间隔呈室性二联律(即短、长间歇交替出现)。文氏现象可使心律失常心电图变得更加复杂,常常有着重要的临床意义。 Wen’s phenomenon is a special form of conduction block, it often occurs in the atrioventricular junction. This case of ectopic pacing in the transfer of atrioventricular junction, because of the presence of retrograde block, so there is no retrograde P ’wave; but the occurrence of downwind (3: 2) block, the performance of the RR interval was Sexual dual law (that is, short, long intermittent appear intermittently). Wen’s phenomenon makes the arrhythmia ECG becomes more complicated, often has important clinical significance.
