Kenwright, D. A. and Bahraminisab, A. and Stefanovska, Aneta and McClintock, Peter V. E. (2008) The effect of low-frequency oscillations on cardio-respiratory synchronization. European Physical Journal B, 65 (3). pp. 425-433. ISSN 1434-6028Full text not available from this repository.
We show that the transitions which occur between close orders of synchronization in the cardiorespiratory system are mainly due to modulation of the cardiac and respiratory processes by low-frequency components. The experimental evidence is derived from recordings on healthy subjects at rest and during exercise. Exercise acts as a perturbation of the system that alters the mean cardiac and respiratory frequencies and changes the amount of their modulation by low-frequency oscillations. The conclusion is supported by numerical evidence based on a model of phase-coupled oscillators, with white noise and lowfrequency noise. Both the experimental and numerical approaches confirm that low-frequency oscillations play a significant role in the transitional behavior between close orders of synchronization.
