起源于左前分支并行节奏点性室速伴文氏型传出阻滞较为罕见,现报道1例如下。男,24岁,因疲劳后出现阵发性心悸、胸闷1天,疑为心肌炎在本院门诊就诊。附图为就诊时描记的心电图。心电图分析各导联均见窦性心律,窦性 P-P 间距为0.86秒,均齐,频率70次/分。同时有过早出现的 QRS波,与其前窦性心搏的联律间距不等,过早搏动的QRS 液在Ⅰ导联呈 rS 型.Ⅲ导联呈 qR 型,电轴右偏115度,符合左后分支阻滞图型,在 V1导联的过早搏动呈 rsR′型,QRS 波时间为0.11秒,呈不完全性右束支阻滞形态,经推算早搏呈并行节奏点性,其周期为0.44～0.46秒。值得注意的是第三行的Ⅰ导联记录呈并行节奏点性室速伴文氏型传出阻滞。并
Rhythm originated in the left anterior branch of the rhythm of ventricular tachycardia with the type of block is relatively rare, is reported in 1 case as follows. Male, 24 years old, due to fatigue after paroxysmal palpitations, chest tightness 1 day, suspected myocarditis in our hospital clinic. The picture shows the electrocardiogram traced at the time of visit. Electrocardiographic analysis of all leads were seen sinus rhythm, sinus P-P spacing of 0.86 seconds, are homogeneous, the frequency of 70 beats / min. At the same time there premature QRS wave, and its pre-sinus heartbeat distance between the joint law, premature beating QRS solution in the lead Ⅰ was rS type Ⅲ lead was qR type, the right axis of 115 degrees, in line with the left Posterior branch block pattern, premature beat V1 lead was rsR ’type, QRS wave time was 0.11 seconds, showed incomplete right bundle branch block morphology, the presumed premature beat was a parallel rhythm point, the cycle is 0.44 ~ 0.46 seconds. It is noteworthy that the third line of the lead Ⅰ was recorded in rhythm of ventricular tachycardia accompanied by Wen-style block. and
