A method to estimate the modulation characteristics of the heart rate by autonomic nervous activities has been discussed. The heart rate (HR) and a calibrated instantaneous lung volume (ILV) signal were simultaneously recorded from fourteen healthy male subjects in variety of conditions including the application of autonomic blocking agent. Randomized breathing technique has been introduced to estimate accurately the transfer characteristic from ILV to HR. The spectral analysis of the heart rate together with estimated transfer characteristics from ILV to HR revealed that the respiratory fluctuations in HR are originated from the parasympathetic nervous activity. This result shows the possibility of non invasive estimation of parasympathetic autonomic modulation of the heart rate. The method will provide us of a new method for the characterization of the heart rate variability.
