Literature reports many computer methods for enhancement of resolution of recorded signals.
Most often the proposed methods are based on the Fourier transform, convolution and deconvolution methods, filtration etc. In a practically unchanged version we applied this program for analysis of ECG signals. It is known that sometimes there can be no changes in the standard ECG despite the evidence of coronary arteries disease or myocardial infarct. Analysis of high-resolution ECG enables detection of electric activity of individual fragments of the cardiac muscle which opens up a possibility of developing a qualitatively new diagnostic method and a means to control the efficiency of treatment of cardiac muscle ischaemia. This vectorcardiogram is obtained as a result of recording in three planes frontal, transversal and sagittal, of the movement of the tip of transient vector of the septum, left and right ventricles depolarisation during a single cardiac muscle evolution, see Fig. 1.
