例1,女,14岁,主因头晕、气紧,脉缓3个月,晕厥1次,于1985年3月8日来我院就诊,诊断为心肌炎。图1为心电图V1、5导联,显示窦性频率100次/分,P波与QRS波群无关。缓慢的QRS波群宽大畸型,同一导联可见到2种形态:其一,V1呈QS型,V5呈qr型,频率41次/分,时限0.12秒;其二,V1呈rS型,V5呈RS型,频率42次/分,时限0.14秒;V5导联除了上述的两种形态以外,可见到第三种形态的QRS波群,呈r型,时限0.07秒,考虑为室性融合波。心电图诊断为:完全性房室传导阻滞,双重性室性逸搏及逸搏心律(均源自右心室)伴心室内干扰。
Example 1, female, 14 years old, mainly due to dizziness, tightness, pulse slow 3 months, syncope 1, in March 8, 1985 came to our hospital for diagnosis of myocarditis. Figure 1 ECG lead V1,5, showing sinus frequency of 100 beats / min, P wave and QRS complex has nothing to do. There are two kinds of morphology of slow QRS wave group, one type is V1, QS type, the other is type qr, the frequency is 41 beats / min, the time limit is 0.12 seconds. Second, V1 is rS type, V5 is RS type, the frequency of 42 beats / min, the time limit of 0.14 seconds; V5 lead in addition to the above two forms, you can see a third form of QRS complex, was r-type, the time limit of 0.07 seconds, considered as a room fusion wave. ECG diagnosis: complete atrioventricular block, dual ventricular escape and escape rhythm (both from the right ventricle) with ventricular interference.
