The paper presents the results of the reproduction of routinely used leads from three corrected orthogonal leads in the system SVEC III modified by L. I. Titomir. Simultaneously with routine and reproduced leads, the differences among them were recorded at every instant of time. In the reproduction for each proband and each lead an individual selection of vector parameters for the given lead was performed. This method was applied in the examination of 150 probands, including 121 patients with myocardial infarction (MI) and 29 healthy subjects. A comparison of routine with reproduced leads showed that in both healthy subjects and patients with MI the limb leads were well reproducible; reproduction of thoracic leads was poorer, especially in patients with MI. Greatest reproduction errors occurred in leads V2 and V3. In 12.5% of patients with anterior-wall infarct, the diagnostically highly important indicators, pathological Q and informative T waves, were not reproduced. The authors assume that in isolated anterior-wall MI, which manifests itself solely in leads V2 and V3, diagnostic errors occur when only three corrected orthogonal leads are used.
本文展示了在由L. I. 季托米尔修改的SVEC III系统中，从三个校正正交导联复制常规使用导联的结果。在记录常规导联和复制导联的同时，还记录了它们在每个时刻的差异。对于每个先证者和每个导联的复制，都针对给定导联进行了矢量参数的个体选择。该方法应用于150名先证者的检查，其中包括121名心肌梗死（MI）患者和29名健康受试者。常规导联与复制导联的比较表明，在健康受试者和MI患者中，肢体导联的复制效果良好；胸导联的复制效果较差，尤其是在MI患者中。最大的复制误差出现在V2和V3导联。在12.5%的前壁梗死患者中，诊断上非常重要的指标，即病理性Q波和有诊断价值的T波，没有被复制出来。作者认为，在仅在V2和V3导联出现的孤立性前壁心肌梗死中，仅使用三个校正正交导联时会出现诊断错误。
