图为患儿的常规12导联心电图:窦性节律,P波的频率79～97次/分,R—R基本规则为56次/分,QRS时间为0.15”,V_1导联呈rsR’示完全性右束枝传寻阻滞, I、aVL呈rS型,S波迟钝,Ⅲ导联呈qR型、QRS电轴+150°示左后分支阻滞,P波与QRS波完全无关,在avL导联可见连续9个P波未下传长达6秒,其后才 出现一个宽大畸形的QRS波,呈qRa型,时间为0.11”的室性逸搏.V_2导联QRS呈两种图型,一种呈Rs型, 一种呈Rsr’S’型交替出现,为单纯性QRS电交替现象.图中TV_1～TV_2深倒,TV_2倒置深达14mm,Q—T间期为0.42”Q—T比值117%,为巨大倒置T波.(本图略有删减)
The picture shows the conventional 12-lead electrocardiogram in children: sinus rhythm, P wave frequency of 79 to 97 beats / min, R-R basic rules of 56 beats / min, QRS time of 0.15 “, V_1 lead showed rsR ’ Complete right bundle branch block, I, aVL was rS type, S wave retardation, type III lead was qR type, QRS axis + 150 ° showed left posterior branch block, P wave and QRS wave has nothing to do in the avL lead shows continuous 9 P-wave was not transmitted for up to 6 seconds, followed by a large abnormal QRS wave, was qRa type, the time was 0.11 ”ventricular escape .V2 lead QRS showed two kinds of maps Type, a kind of Rs type, a kind of Rsr’S ’type alternating for the simple QRS alternating phenomenon TV1 ~ TV_2 deep down, TV_2 upside down to 14mm, Q-T interval was 0.42 "Q-T The ratio of 117%, for the huge inverse T wave.
