A four-electrode resistance-combined network system was used to record the vector-cardiograms of 15 full-term infants, from birth to 96 hours of life. In the horizontal plane the QRS loop was described in a clockwise manner anterior to the point of origin. Initially it was directed anteriorly to the left and, terminally, posteriorly to the right. In the sagittal plane the loop described a figure-of-eight, with minimal superior and inferior displacement of the anterior and posterior components. In the frontal plane the QRS vector loop was described in either a clockwise direction inferior to the point of origin or a clockwise direction superior to the point of origin. Alterations in the appearance of the QRS vectorcardiogram result from changes in spatial orientation.
采用四电极电阻组合网络系统记录了15例足月儿从出生至出生后96小时的心电图向量图。在水平面，QRS环在起始点前方呈顺时针方向描述。起初它向前指向左侧，最终向后指向右侧。在矢状面，环呈8字形，前后部分的上下位移最小。在额面，QRS向量环在起始点下方呈顺时针方向描述，或在起始点上方呈顺时针方向描述。QRS心电图向量图外观的改变是由空间方向的变化引起的。
