Active biomedical media exploration by means of spectral analysis approaches and chaotic signal attractor trajectories investigation

The mathematical model of nervous pulse propagation in the homogeneous nervous fibre is constructed on the basis of spectral analysis methods. 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 to estimate a number of freedom degrees of electrocardiosignal and complexity degree of myocardium dynamics.
