Variations in breathing patterns broaden heart rate variability spectral bands and increase the power amplitude of low-frequency bands, necessitating controlled breathing for accurate comparisons.
Do variations in breathing patterns affect heart rate variability (HRV) spectral bands?
Spectral markers for HRV signals should be compared only under controlled breathing conditions or after considering the effect of variations in breathing patterns.
This paper shows that variations in breathing patterns broaden heart rate variability (HRV) spectral bands and increase the power amplitude of low-frequency bands. Because of these influences, spectral markers for HRV signals, such as the quotient between spectral power at different frequency bands, should be compared only under controlled breathing conditions or after considering the effect of variations in breathing patterns
García-González et al. (Tue,) conducted a other in Heart rate variability analysis. Variations in breathing patterns vs. Controlled breathing conditions was evaluated on HRV spectral bands and power amplitude of low-frequency bands. Variations in breathing patterns broaden heart rate variability spectral bands and increase the power amplitude of low-frequency bands, necessitating controlled breathing for accurate comparisons.
