Autonomic nervous nonlinear interactions lead to frequency modulation between low- and high-frequency bands of the heart rate variability spectrum

Abstract: Chon KH. Autonomic nervous nonlinear interactions lead to frequency modulation between low-and high-frequency bands of the heart rate variability spectrum. Am J Physiol Regul Integr Comp Physiol 293: R1961-R1968, 2007. First published August 29, 2007 doi:10.1152/ajpregu.00362.2007.-Cardiac sympathetic and parasympathetic neural activities have been found to interact with each other to efficiently regulate the heart rate and maintain homeostasis. Quantitative and noninvasive methods used to detect the presenc… Show more

“…Quantitative analysis also found interactions between the two nervous systems. For example, using a combined wavelet and power spectral analysis, we found evidence of interactions between the sympathetic and parasympathetic nervous systems in the form of frequency modulation in the same young control subjects as used in this report (29). Interactions in the form of frequency modulation are also a consequence of the nonlinear properties of systems since nonlinear coupling can take many different forms.…”

“…In contrast to the HOW-transformation, the HH-transformation considers these underlying processes as interacting through phenomenological relevant mode mixing [10,15]. Such interaction of the respiration and baroreceptive sinus arrhythmia is recently reported by Zhong et al [33] who confirmed that phenomenological relevant mode mixing might be present in real RR series. The present results also indicate that the HH-transformation decompose the RR series into fewer (6 ± 1) approximate orthogonal components D k (t) (orthogonal index \ 0.1 [15]) within the HF and LF frequency range (i.e., 0.04-0.4 Hz) when compared to the 2 4 -1 = 15 packets D m (t) of Eq.…”

“…where f k (t) is the derivative of the instantaneous phase / k ðtÞ: Time-frequency analyses which deduce f k (t) and A k (t) for multiple k have arose interest in the investigation of sympaticovagal modulation of the respiration and baroreceptive sinus arrhythmia [e.g., 10,13,14,27,33]. Of these methods, the deduction of a Hilbert-Huang (HH) spectrum [15] through an empirical mode decomposition (EMD) has gained importance.…”

“…In physiological systems, non-linear interactions between feedback mechanisms may include one system modulating the amplitude or frequency of another [1]. Amplitude modulation results in two sinusoids generating a third with a frequency at f 1 + f 2 and a phase equal to φ 1 + φ 2 .…”
