Spectral analysis of blood pressure warrants cautious interpretation; leaves open the relative contributions of individual physiological systems.
Spectral analysis of blood pressure fast oscillations (short-term variability), both in humans and animals, reveals three major frequential domains: the very low-, low- and the high-frequency domain. In this paper, experimental data providing evidence for physiological mechanisms involved in the regulation of blood pressure oscillations such as sympathetic nervous system, renin-angiotensin system, NO, respiration, heart function, and circulating blood volume are reviewed. In addition, novel evidence is provided by the author for vasopressin modulation of the low- and high-frequency blood pressure components. This review suggests that the multiplicity of factors involved in the genesis of the blood pressure spectral components imply utmost caution in interpreting spectral results.
