[State of the peri-infarct and necrotic areas in various complications of myocardial infarct according to ECG data (35 precordial leads)].

On the basis of ECG recorded in 35 precordial leads and subsequent cartographic analysis of the results obtained, the state of the necrotic and periinfarction zones in 38 patients with complicated myocardial infarction (development of circulatory insufficiency, acute aneurysm of the left ventricle, and pericarditis epistenocardica) was analysed. In circulatory insufficiency being the only complication, significantly smaller values of the indices characterizing the necrotic and periinfarction zones were found. In pericarditis, dynamics of the most mobile ECG indices was observed which characterized the state of the periinfarction zone in the direction of diminution (by half) by the end of the 1st week; in aneurysm the same degree of diminution was noted only by the end of the 2nd week of the process. In fatal outcomes of the disease these indices fluctuated within the range of the individual levels of the initial values without showing any obvious tendency to decrease in the first 2 weeks of the disease.
