The very low-frequency band of heart rate variability represents the slow recovery component after a mental stress task
The very low-frequency (VLF) band of heart rate variability (HRV) has different characteristics compared with other HRV components. Here we investigated differences in HRV changes after a mental stress task. After the task, the high-frequency (HF) band and ratio of high- to low-frequency bands (LF/HF) immediately returned to baseline. We evaluated the characteristics of VLF band changes after a...
متن کاملMetabolic Rate Variability Impact on Very Low-Frequency of Heart Rate Variability
There is an opinion that the very-low-frequency (VLF) fluctuations of heart rate’s variability (HRV) have been associated with energetic process in organism. The background of this study was the hypothesis that VLF variability of respiratory pattern (VRP) is influenced by oxygen consumption (VO ) regulation. 2 However, it is still unclear: is there a correlation between those processes? The goa...
متن کاملStress Recovery Effects of High- and Low-Frequency Amplified Music on Heart Rate Variability
Sounds can induce autonomic responses in listeners. However, the modulatory effect of specific frequency components of music is not fully understood. Here, we examined the role of the frequency component of music on autonomic responses. Specifically, we presented music that had been amplified in the high- or low-frequency domains. Twelve healthy women listened to white noise, a stress-inducing ...

Low-frequency component of the heart rate variability spectrum: a poor marker of sympathetic activity.
The low-frequency component of the heart rate variability spectrum (0.06-0.10 Hz) is often used as an accurate reflection of sympathetic activity. Therefore, interventions that enhance cardiac sympathetic drive, e.g., exercise and myocardial ischemia, should elicit increases in the low-frequency power. Furthermore, because an enhanced sympathetic activation has been linked to an increased prope...
