本文总结分析74例心房间隔缺损的心电图特征。认为:继发孔型电轴多数右偏,而原发孔型多数左偏;QRS形态在房缺中多数表现不全右或完全右束枝阻滞图象;根据QRSV_1时限可粗略判断缺损大小;按照QRSV_1形态可大致估计肺:体流量的多少,对术前诊断有一定意义,故具有临床价值。
This article summarizes the analysis of 74 cases of atrial septal defect ECG characteristics. The results showed that most of the primary perforations were left-sided and the majority of the primary perforations were left-sided. Most of the QRS morphology showed incomplete right or complete right bundle-branch block in the atrial septum, and the defect size could be roughly judged according to QRSV_1 time- In accordance with the QRSV_1 morphology can be roughly estimated lung: the amount of body fluid, preoperative diagnosis of some significance, it has clinical value.
