The changes in the corrected orthogonal electrocardiograms of 411 patients were analyzed: 134 with right ventricle loading, 137 with left ventricle loading and 140 with myocardial infarction (chronic phase). On the base of sensitivity and specificity criteria the indices SXmV, SXmsec and QZmV for the patients with right ventricle loading and RXmV and RZmV for the patients with left ventricle loading proved to be with the highest diagnostic value. Sensitivity is within 19% to 61%. Sensitivity is within 85% and 95% in patients with myocardial infarction (chronic phase), for the different indices depending on the infarction zone. The comparative analyses of the indices of the corrected orthagonal Frank electrocardiogram and the standard electrocardiogram (12 leads) give a certain preference to the indices of the standard electrocardiography.
分析了411例患者校正正交心电图的变化：134例右心室负荷患者、137例左心室负荷患者和140例心肌梗死（慢性期）患者。根据敏感性和特异性标准，右心室负荷患者的指标SXmV、SXmsec和QZmV以及左心室负荷患者的指标RXmV和RZmV具有最高的诊断价值。敏感性在19%至61%之间。心肌梗死（慢性期）患者的敏感性在85%至95%之间，不同指标取决于梗死区域。校正正交Frank心电图指标与标准心电图（12导联）指标的比较分析对标准心电图指标有一定的偏好。
