Possibility Analysis of Preserving the ST Segment Shift when Approximated by Gaussian Pulses

In this paper, a virtual device for automatic determination of parameters of approximate asymmetric Gaussian curves in the Labview software environment for analysis of electrocardiographic signals is improved. The introduction of piecewise linear functions in the sections of individual waves prevents the disappearance of horizontal sections that have a vertical offset relative to the isoline. As a result, the possibility of preserving the displacement of the horizontal section of the ST segment, which carries diagnostically important information, is shown.
