这帧心电图乍一看,QRS呈多种形态。基本心律PH倒置,P”-R<0.12”(=0.08”),QRS呈RS型,时限为0.10“,P”-P”匀齐,频率约83次/分,考虑为加速性交界性自主节律。此外,可见两种提前出现的宽大畸形之QRS-T波群,分别呈rS型和qR型,时限均 This frame of ECG at first glance, QRS was a variety of forms. The basic rhythm of ventricular arrhythmias was inverted, P “-R <0.12” (= 0.08 “), QRS was RS, with a time limit of 0.10” and P “-P” homogeneous with a frequency of about 83 beats per minute, considered as accelerating borderline autonomic Rhythm. In addition, there are two kinds of QRS-T wave swarms that appear prematurely, which are rS type and qR type respectively,
