Frequency of the blood pressure spectral peak around 0.1 Hz and baroreflex sensitivity in man
Popis výsledku v původním jazyce
According to the mathematical model of the vascular component of baroreflex, the gain of the heart-rate baroreflex sensitivity (BRS) positively correlates with the resonance frequency of the peak in the range of 0.05 - 0.15 Hz. In this study the relationship between BRS and the frequency of the peak in blood-pressure (BP) spectra around 0.1Hz was evaluated 58 subjects at rest and during exercise. A positive correlation between the frequency of the peak in BP-spectra around 0.1 Hz and BRS was confirmed during exercise and during the recovery period respectively. At rest this correlation was not found. This could be explained by the role of autonomic nerves in blood-pressure and heart-rate regulation. BRS mainly corresponds to the gain of parasympatheticactivity, which is high at rest. Sympathetic activity, which determines vascular resistance, dominates during exercise.
