摘要
A method and apparatus for non-invasive, real-time monitoring of the autonomic nervous systems using non-stationary spectral analysis of both heart rate and respiratory signals. Continuous wavelet transformation is used in real-time so that the dynamic interactions between the sympathetic and parasympathetic divisions of the autonomic nervous system can be independently monitored in the frequency domain. The method in accordance with the present invention allows spectral analysis, formerly limited to the study of stationary data, to be applied to time-varying biological data such as heart rate variability and respiratory activity. In addition, the same techniques are used to monitor other biological or physiological data, including blood pressure.
