title: [The diagnostically significant indices of the corrected axial ECG system in the differentiation of ischemic heart disease and dilated cardiomyopathy].
abstract: The common uniformity of electrocardiographic changes in coronary heart disease (CHD) and dilated cardiomyopathy (DCMP) in the lead XII, namely low QRS complex voltage, T-wave inversion, cardiac arrhythmias, atrioventricular and intraventricular conduction disturbances, served as the basis for searching for individual or combined lesion signs quantitatively diagnostically significant for CHD and DCMP. For this purpose, 217 patients were examined. Out of them 83 were included into a group of healthy persons and 134 were patients who were divided into two groups: 60 with chronic CHD and 74 with DCMP. The authors identified a complex of diagnostically significant ECG parameters of the McPhi-Parungao system. SX > 4 mm, SZ > 12 mm, RX + SZ > 27 mm, sigma RXYZ + sigma SXYZ > 45 mm, sigma RXYZ/sigma SXYZ < 1.5, which permits differentiation of DCMP and CHD in case of lowered QRS voltage on ECG-12.
