title: [Size of the postinfarct scar and the functional state of the left ventricle].
abstract: Forty-five patients who had suffered from anterior myocardial infarction were examined by echocardiography in the M regimen and ECG recorded from 35 precordial leads. According to the extensiveness of the postinfarction scar, the patients were divided into 3 groups. The results of the examination showed that the value of the Q index (the number of leads with an abnormal Q wave) correlates with the clinical signs of circulatory insufficiency, the values of the systole and diastole phase analysis has a positive correlative connection with the end-diastolic volume of the left ventricle and the value of mitral-septal separation, but does not correlate with such values as the ejection fraction, the rate of circulatory shortening of the myocardial fibers and the degree of shortening of the left-ventricular small axis, which are calculated from the echocardiogram in the M regimen.
