Spectral analysis of heart rate variability measures these fluctuations in a frequency-specific way.
Spectral analysis of heart rate variability has been suggested for detecting both sympathetic and parasympathetic failure[12, 13].
The purpose of this study was to find out whether spectral analysis of heart rate variability is useful in evaluating sympathetic function in elderly subjects by comparing the change of heart rate variability in the LF spectral band during head-up tilt with the plasma noradrenaline response to head-up tilt in elderly hypertensives and diabetics.
It seems reasonable to assume that in spectral analysis of heart rate variability in the elderly, sympathetic activation manifests itself rather as a change in sympathovagal interaction (relative LF power, LF/ HF ratio) than as a change in absolute LF power.
Our results indicate that spectral analysis of heart rate variability can be considered a useful tool in evaluating sympathetic function in elderly subjects.
