Abstract: The classic “control system theory” approach was used to find the transfer function (TF) of the HR control system with respiratory input. Eight healthy subjects, ages 19–40 participated in the study. Paced breathing at seven frequencies in 0.5– 0.04 Hz range was used as sine-wave stimuli to assess the HR control system. The sine-wave HR oscillation in response to each stimulus as the system’s output was recorded. Amplitude and phase TFs were calculated for each frequency separately. The Fourier filtration procedure was used for TF calculation. Experimentally obtained TFs revealed the same important features in all participants: 1) the amplitude TF had its peak in a narrow frequency range around 0.1 Hz; 2) the phase TF successively changed from positive to negative when breathing frequency increased, and passed “0” at frequency where the amplitude TF peaked; 3) the peak frequency and magnitude were unique for each participant. These features are evidence for the resonance property of t he HR control system at a frequency around 0.1 Hz. This study suggests that accurate identification of an individual’s resonance frequency can be found using the TF features of HR control system and controlled breathing techniques. (More)
