A signal analysis method based on Entropy, Lyapunov exponent and Multiscale Entropy is proposed to estimate the complexity of long-range temporal correlation heart rate variability time series for an elderly person and a young person, both healthy. These new methods could improve the overall understanding of the physiological system of the human organism and its state of health by assessing the level of complexity and of chaos of the biodynamic signal. By adopting new models and experimental paradigms, such as those of fractality and entropy, which have the ability to direct from an organ medicine to a modern systemic medicine.
