临床资料:女,62岁,临床诊断:缺血性心脏病。心电图特征:本图上下两行系V_1导联的连续记录。图示窦性P波的形态时间正常,但P-P间距不规则,呈长短交替,长P-P间距为1.48秒,短P-P间距为1.10秒,QRS波分别呈rS型及rsR′型和rsr′型三种形态。前者形态时间均正常,但节律与P波一样呈长短周期交替出现。长的R-R间期为1.58秒,短的R-R间距为1.04秒。后二种QRS波均相随前-QRS波后0.56秒～0.58秒处出现,其前均可见一窦性P波,P-R间期为0.30～0.36秒。心电图诊断:1.双结性文氏现象:(1)二度Ⅰ型窦房传导阻滞呈3:2传导:(12)加速的房室交界区逸搏心律伴文氏现象。
Clinical data: Female, 62 years old, clinical diagnosis: ischemic heart disease. ECG features: The upper and lower lines of this figure V_1 lead continuous recording. The sinusoidal P wave morphological time is normal, but the PP pitch is irregular, with an alternation of length and length. The long PP interval is 1.48 seconds and the short PP interval is 1.10 seconds. The QRS waves are rS and rsR ’and rsr’ Species. The former morphological time are normal, but the rhythm and P wave was the same length and length of the cycle alternately. The long R-R interval is 1.58 seconds and the short R-R spacing is 1.04 seconds. After the two QRS wave with the pre-QRS wave 0.56 seconds ~ 0.58 seconds after the appearance of a sinus P wave can be seen before, P-R interval 0.30 ~ 0.36 seconds. ECG diagnosis: 1. Double knot Wen’s phenomenon: (1) second-degree sinoatrial block conduction was 3: 2 conduction: (12) accelerated atrioventricular junctional escape rhythm with Wen’s phenomenon.
