The results are presented of comparison of electrocardiographic data obtained in 36 precordial and 6 standard precordial leads of ECG, and their correlation degree in 20 patients with acute transmural myocardial infarction (MI). Total R-wave and QS complex amplitude, the number of leads recording the mentioned changes (nR and nQS), total ST-segment elevation (epsilon ST) and the number of leads with ST elevation greater than or equal to 1 mm were assessed. The study demonstrated that R-wave and QS complex amplitude, and also the number of informative leads recording these changes were the most reliable markers of ischemia and necrosis. High authenticity of data in 6 leads-standard ECG and accurate correlation of examined indices with similar ones in 36 precordial leads throughout the observation at various points of the testing suggest that the treatment of QRS complex in 6 lead-standard ECG gives a reliable assessment of the prevalence and time course of ischemic myocardial damage in patients with anterior transmural myocardial infarction.
本文给出了对20例急性透壁性心肌梗死（MI）患者在36个胸前导联和6个标准胸前导联心电图中获得的心电图数据进行比较的结果，以及它们之间的相关程度。评估了总R波和QS波群振幅、记录上述变化的导联数量（nR和nQS）、总ST段抬高（εST）以及ST段抬高≥1mm的导联数量。研究表明，R波和QS波群振幅以及记录这些变化的信息性导联数量是缺血和坏死最可靠的标志物。在整个观察期的不同测试点，6导联标准心电图数据的高真实性以及所检查指标与36个胸前导联中类似指标的准确相关性表明，对6导联标准心电图中QRS波群的分析能够可靠地评估前壁透壁性心肌梗死患者缺血性心肌损伤的发生率和病程。
