房性早搏伴折返途径中的文氏现象已有报道,而逆文氏现象则较罕见,现报道1例。患者女性,17岁,临床诊断:病毒性心肌炎。心电图(见第171页)Ⅱ、Ⅴ_1导联示每1个窦性搏动后连续提早出现与窦P形态不同的P_1′、P_2′,该两P′形态一致。P_1′重叠于T波顶峰及下降支上,Ⅱ导联有2个P_1′下传心室呈左束支阻滞型,其P_1′R间期0.22秒,此时P_2′重叠于QRS波上而阻滞,Ⅱ导联另有3个P_1′及V_1导联P_1′隐匿性地激动了房室交界处使其产生新的不应期,以致出现在舒张早中期的P_2′不能下 Ventricular premature beats with the return pathways have been reported in the phenomenon, while the reverse Wen’s phenomenon is rare, is reported in 1 case. Patient female, 17 years old, clinical diagnosis: viral myocarditis. Electrocardiogram (see page 171) II, â ... ¢ lead showed every sinus beats after a continuous premature sinus and P sinus P morphology different P_1 ’, P_2’, the two P ’morphology consistent. P_1 ’overlaps the peak and descending branch of T wave. There are 2 P_1’ descending branches in Ⅱ lead with left bundle branch block. The P_1’R interval is 0.22s, when P_2 ’overlaps with QRS wave Block, Ⅱ leads another three P_1 ’and V_1 lead P_1’ hid the excitement of the atrioventricular junction so that it produces a new refractory period, resulting in early diastolic P_2 ’can not
