Interaction between resting pulmonary ventilation function and cardiac autonomic function assessed by heart rate variability in young adults

Abstract

An association between ambient air pollution and reduced cardiac autonomic function assessed by heart rate variability (HRV) mainly in elderly persons has been suggested by a number of epidemiological studies, but the link between the HRV and pulmonary function in humans remains unknown although such air pollution should primarily affect pulmonary function. To clarify this link, pulmonary ventilation parameters such as oxygen uptake (V 4O 2 ) and carbon dioxide output (V 4 CO 2 ), as well as the HRV with spectral analysis (high-and low-frequency components of HRV, i.e., CCV HF and CCV LF , reflecting cardiac parasympathetic and sympathetic activities, respectively), were measured in 66 healthy women aged 19-20 years after an overnight fast of 12 h. Significant correlations were found between the CCV HF of HRV and both the end-tidal carbon dioxide concentration (FETCO 2 ) and gas exchange ratio (V 4 CO 2 /V 4 O 2 ) in the subjects (partial correlation coefficients r = 0.354 and 0.320, respectively), whereas there was no significant connection between the FETCO 2 and the V 4 CO 2 /V 4 O 2 . Similarly, the CCV LF correlated significantly with the resting tidal volume of lung (r = 0.364). These findings suggest that resting pulmonary ventilation function interacts with cardiac autonomic function assessed by the HRV, at least in healthy young adults, which may be useful for explaining the pathophysiology concerning the short-term effect of air pollution such as fine particulate matter on cardiovascular function.

The effect of therapeutic horseback riding on heart rate variability of children with disabilities

“…An increase in CCV HF indicates an increase in parasympathetic activity and increase in CCV LF indicates an increase in sympathetic activity (Kurosawa et al . 2007). Component coefficient of variance for LF showed a significant increase from session three to session four ( p = 0.0006), and session six was also significantly higher than session one ( p = 0.022) and four ( p = 0.011), during THR (Figure 3).…”

“…CCV high frequency (HF) and CCV low frequency (LF) reflect the parasympathetic and sympathetic activity, respectively (Kurosawa et al . 2007). …”

Effects of Several Environmental Factors on Longevity and Health of the Human Population of Zhongxiang, Hubei, China

“…Many studies have found that air polluted with SO 2 and inhalable particulate particles can harm human health and lead to many diseases. Air polluted with SO 2 can lead to cardiovascular diseases [25][26][27][28][29], ischemic heart disease [30], and pulmonary heart disease [31]. Particulate matter in air is related to human health to a certain degree.…”
