Nonlinear dynamics methods application to electrocardiosignal exploration

Abstract

The results of digitized cardiosignal investigation on the basis of nonlinear dynamics approach (local-topological analysis of chaotic attractor trajectories) and spectral analysis methods (fast Fourier transforming) are represented. It is shown that the local-topological analysis of phase trajectories allows one to estimate a number of degrees of freedom of the electrocardiosignal and complexity degree of myocardium dynamics.
