Periodical fluctuation observed in measured R-R interval series of the ECG reflects various functional changes of the autonomic nervous system. Many previous studies reported that low and high frequency components obtained from spectral analysis for the R-R interval series can be effective indices to estimate the autonomic function. In this study, to optimize the frequency ranges for the assessment of the autonomic function, R-R interval series of the ECG were recorded during physical exercise (using the Ergometer or Master's "two-step" test) and mental tasks with adult subjects. Indicator values on the autonomic function were calculated with numerical integration of R-R spectra in 12 kinds of frequency ranges. Frequency ranges which were clearly discriminated between the physical exercise and the control condition were different from those for the mental task and the control condition. Therefore, some attention should be paid in practical use of this technique.
