A homogeneous model of rabbit torso and physical dipole are used. A comparison is made between the corrected orthogonal vectorcardiographic lead systems after Frank, McFee-Parungao and Zao. The components X, Y, Z of the lead vectors are measured for 15 points which can be inserted in the cardiac volume under normal conditions. The modules of the lead vectors and the angles between them are calculated. The three vectorcardiographic systems are compared with respect to the ratio between the modules (X:Y:Z) and the deviations of the angles from the real value. Best orthogonality are found with the system after Frank, if the thoracic electrodes are placed precisely at the level of the so-called electrical cardiac centre. No essential differences are found between the systems after Frank and after McFee-Parungao with respect to correctedness and orthogonality.
使用了兔躯干的均匀模型和物理偶极子。对Frank、McFee-Parungao和Zao之后的校正正交向量心电图导联系统进行了比较。测量了在正常情况下可插入心脏容积内的15个点处导联向量的X、Y、Z分量。计算了导联向量的模及其之间的夹角。从模之间的比例（X:Y:Z）以及角度与真实值的偏差方面对这三种向量心电图系统进行了比较。如果胸部电极精确放置在所谓的心电中心水平，则Frank之后的系统具有最佳正交性。在校正性和正交性方面，Frank之后的系统与McFee-Parungao之后的系统之间未发现本质差异。
