The paper proposes new criteria for differential diagnosis of myocardial "focal scarring" and "++pseudo-scarring" changes in various cardiac abnormalities and homogeneous morphological alterations in the ventricular complex on ECG (the QS, Qr-type abnormalities of the R line) by using the findings of 35 lead ECG mapping (PM-35). ECG-12 and PM-35 were analysed in 427 patients, including those with coronary heart disease (n-122), arterial hypertension and aortic malformations (n-130), dilated cardiomyopathy, congenital cardiac disease (n-175). Electrocardiographic signs of focal scarring lesions were revealed in all the cases with coronary heart disease and 66 with myocardial hypertrophy. The total value of ST segment depression and the sum of Q wave squares in three to five vertical mapping columns were found to be the most significant differential and diagnostic criterion. When scars and ++pseudo-scars were differentiated, a sensitivity of 75% was obtained at a specificity of 87%.
本文提出了新的标准，用于鉴别诊断各种心脏异常情况下心肌“局灶性瘢痕形成”和“++假性瘢痕形成”变化，以及通过使用35导联心电图标测（PM - 35）结果来鉴别心电图上心腔复合波的均匀形态改变（R波的QS、Qr型异常）。对427例患者的12导联心电图和PM - 35进行了分析，包括冠心病患者（n = 122）、动脉高血压和主动脉畸形患者（n = 130）、扩张型心肌病患者、先天性心脏病患者（n = 175）。在所有冠心病病例和66例心肌肥厚病例中均发现了局灶性瘢痕形成病变的心电图征象。发现三到五个垂直标测列中ST段压低的总值和Q波平方和是最显著的鉴别诊断标准。在区分瘢痕和++假性瘢痕时，敏感性为75%，特异性为87%。
