[Use of integral indicators of precordial mapping in differential diagnosis of focal-cicatricial lesions of the myocardium].
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%.
