Abstract :
The paper presents the main principles for obtaining enhanced resolution in standard ECG records, constructing of high-resolution vectorcardiogram and determining of activities of particular segments of the cardiac muscle. Standardized electric activities of the ventricles and septum in healthy people are given. Electric activities of particular fragments of the cardiac muscle were measured by the HRVEC method for a group of healthy subjects and for people subjected to SPECT or coronarographic examination.
