Does normalized low-frequency heart rate variability power correlate with heart rate during incremental head-up tilt in young healthy males?
The demonstrated linear relation between normalized low-frequency heart rate variability power and heart rate confirms the potential of heart rate variability as a noninvasive means of assessing sympathovagal balance.
