[Electrophysiological methods of assessing myocardial hypoxia].

The potentialitis of the standard electrocardiogram, precordial cartogram and spatial analysis are confronted in 38 patients with extensive anterior or anteroseptal myocardial infarction, acute phase, in order to determine the extent and propagation of the myocardial hypoxia. The determination is performed on the base of the correlation dependence as regards the creatinine-phosphokinase level in blood. The best degree of correlation dependence has the spatial analysis of the changes in the segment ST - Vmax ST sp. r=0.69, as well as the changes in the segment ST reflected in the precordial electrocardiography - nST-0.1 mv. r=0.67. Close is the degree of correlation dependence in the standard electrocardiogram - STv r=0.59. The difference in the correlation coefficients are not statistically significant, allowing their application in the routine work of the three methods.
