The findings of the VCG automatic construction in 55 healthy subjects with different axial and positional variants of ECG were analyzed . The applied method of the automatic corrected VCG construction has shown that QRS loop morphology coincides with the classical forms of VCG described before in healthy persons. The data of the automatic calculations of spatial characteristics demonstrated the orientation stability according to the angle--azimuth, max QRSxyz , S/2 QRSxyz and the integral vector-- AQRSxyz , i. e. independence of the azimuth value on the ECG axial and positional variants. The positional and rotational shifts regularly change the azimuth value in the spatial orientation of the initial (0.01"--0.02') and end (0.06") moment vector of depolarization, and the value of the angles of spatial vector elevation max QRSxyz , S/2 QRSxyz , AQRSxyz . In the normal intraventricular conduction, the orientations of max QRSxy , yz , xz are sufficiently informative in order to reveal the integral vector directions. The coincidence of S/2 QRSxy , yz , xz direction with that of AQRSxy , yz , xz in the two-polar loops indicates that S/2 QRSxy , yz , xz should be calculated to determine AQRSxy , yz , xz orientation. Indeed, in case of intraventricular conduction disorders, the AQRSxy , yz , xz calculation alone gives an idea of a resultant vector projection.
分析了55名具有不同心电图轴位和位置变异的健康受试者的VCG自动构建结果。应用的自动校正VCG构建方法表明，QRS环形态与之前描述的健康人VCG经典形态一致。空间特征自动计算的数据显示，根据角度——方位角、最大QRSxyz、S/2 QRSxyz和积分向量——AQRSxyz，其方向具有稳定性，即方位角值与心电图轴位和位置变异无关。位置和旋转移位会定期改变去极化初始（0.01"——0.02'）和结束（0.06"）时刻向量空间取向中的方位角值，以及空间向量仰角最大QRSxyz、S/2 QRSxyz、AQRSxyz的值。在正常室内传导时，最大QRSxy、yz、xz的方向对于揭示积分向量方向具有足够的信息量。在双极环中，S/2 QRSxy、yz、xz方向与AQRSxy、yz、xz方向一致，这表明应计算S/2 QRSxy、yz、xz以确定AQRSxy、yz、xz的方向。实际上，在室内传导障碍的情况下，仅计算AQRSxy、yz、xz只能给出合成向量投影的概念。
