[Vectorcardiographic mapping in the evaluation of the severity of myocardial infarct]

Using the method of multidipol vector charting, the chronotopography of the potentials of the electric field of the heart in the precordial region was studied in 98 patients with acute myocardial infarction. Qualitative criteria of the severity of the course of myocardial infarction of various localization were obtained by using a phasic analysis of ventricular loops of vector cardiograms. The proposed method of vector cardiographic charting characterizes the functional status of the myocardium and may be used for determining the size of the necrotic zone in clinical and experimental conditions.
