摘要

介绍了基于非线性动力学方法(混沌吸引子轨迹局部拓扑分析)和频谱分析方法(快速傅立叶变换)的数字化心脏信号研究结果。结果表明，相位轨迹的局部拓扑分析可以估计心电信号的多个自由度和心肌动力学的复杂程度。

Nonlinear dynamics methods application to electrocardiosignal exploration

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.
