Estimation of size of infarcted focus by spatial quantitative vectorcardiography in patients with acute anterior myocardial infarction.
The study included 113 patients with acute myocardial infarction of the left ventricular anterior wall. The patients were repeatedly followed up from the first hours of the affection onward in the course of the individual stages of treatment (stage of intensive monitoring and therapy; intermediate stage; initial rehabilitation with application of active therapy; early mobilization, activation and rehabilitation). A new approach to the estimation of the size of the infarcted focus is described, namely, the method using spatial quantitative vectorcardiography. It was found that the spatial localization of the 40-ms vector, especially its azimuth, is a specific indicator, with the aid of which the localization, extent and depth of the lesion in the left ventricular anterior wall can be assessed with a high probability in most instances. The compensatory adaptive and reparative capacity of the affected myocardium, estimated on the basis of spatial quantitative VCG, is closely correlated with the size of the infarcted focus.
