(Multi)fractality of physiological time-series

This paper contains the application of fractal concept in analysing heartbeat (RR interval) fluctuations measured under controled physical activity for subjects with stable angina pectoris (SAP). Results that illustrate the separation ability of the nonlinear methods, such as the Hurst R/S method, the detrended fluctuation analysis, DFA, and the method of G-moments, in distinguishing healthy from SAP subjects in scaling parameter space are presented.
