Abstract

This invention is an apparatus for time dependent power spectrum analysis of a physiological signal modulated by the autonomic nervous system. The apparatus includes a sensor (102) for picking up a physiological signal modulated by the autonomic nervous system and a frequency selection apparatus (122) for selecting at least one frequency inherent to the signal. The apparatus further includes a selective windowed time-frequency analysis processor (104) for determining the power spectrum of the physiological signal within a window along the signal for the at least one frequency, and an output apparatus (154) for providing information associated with the functioning of the autonomic nervous system as provided by the power spectrum of the physiological signal.
