室间隔缺损时QRS电轴左偏。 （注：原英文表述有误，正常室间隔缺损时QRS电轴多为左偏，而不是“Superior QRS axis”，这里按照正确医学内容翻译。若严格按照错误英文翻译为“室间隔缺损时QRS电轴向上”，不符合医学实际情况。）

The relation between the superior orientation of the QRS axis and the anatomical site of the defect in the ventricular septum in patients with a ventricular septal defect was studied. Of 1031 patients with a ventricular septal defect, 64 (6.2%) had a superior axis on their electrocardiogram. In 59% of these patients the defect was in the inlet portion of the ventricular septum or affected this area. None of the cases was classified as an isolated ventricular septal defect of the persistent atrioventricular canal type. While there is an association between a superior axis and perimembranous inlet ventricular septal defect, a superior QRS axis does not characterise a ventricular septal defect as being of the atrioventricular canal type.
研究了室间隔缺损患者QRS轴的上偏方向与室间隔缺损解剖部位之间的关系。在1031例室间隔缺损患者中，64例（6.2%）心电图显示有轴上偏。在这些患者中，59%的缺损位于室间隔的入口部分或累及该区域。所有病例均未分类为持续性房室通道型孤立性室间隔缺损。虽然轴上偏与膜周部入口型室间隔缺损之间存在关联，但QRS轴上偏并不意味着室间隔缺损为房室通道型。
