A comparison of electrocardiographic and anatomic data was made in 74 patients with acute myocardial infarction with the purpose of investigating QRS-complex changes in macrofocal myocardial infarction, and establishing the correlation between ECG data and the volume of the infarcted myocardium. It has been shown that subendocardial and transmural necrosis of the anterior wall of the left ventricle was in all cases reflected on ECG by QS, while transmural necrosis of the posterior wall was associated in 86% of the cases with the presence of QR, Qr or qR on ECG. Thus, the estimation of myocardial necrosis depth by ECG data is difficult. An increase in myocardial necrosis area is paralleled by an increase in Q wave duration, in Q/R ratio value, and by a decrease in R wave amplitude. There was no significant linear correlation between the volume of necrosis area and the amplitude of Q wave of the number of ECG leads in which signs of myocardial infarction were detected.
对74例急性心肌梗死患者的心电图和解剖学数据进行了比较，目的是研究大片局灶性心肌梗死时QRS波群的变化，并建立心电图数据与梗死心肌体积之间的相关性。结果表明，左心室前壁的心内膜下和透壁性坏死在所有病例中在心电图上均表现为QS波，而后壁透壁性坏死在86%的病例中与心电图上出现QR、Qr或qR波有关。因此，通过心电图数据估计心肌坏死深度是困难的。心肌坏死面积增加与Q波时限增加、Q/R比值增加以及R波振幅降低并行。坏死面积体积与检测到心肌梗死征象的心电图导联Q波振幅数量之间无显著线性相关性。
