A dampening effect of pulse interval variability on blood pressure variations with respect to primary variability in blood pressure during exercise.
Original language description
The correlation between baroreflex sensitivity (BRS) and the component of spectrum at a frequency of 0.1Hz of pulse intervals (PI) and systolic blood pressure (SBP) was studied. SBP and PI of 51 subjects were recorded beat-to-beat at rest, during exercise and during recovery. BRS was determined by a spectral method. The subjects were divided into groups according to the spectral amplitude of SBP at a frequency of 0.1 Hz: very high (vh); high (h); middle (m), low (l). The 0.1 Hz variability of PI increased significantly with increasing BRS in each of the groups with the identical 0.1 Hz variability in SBP. This relationship was shifted to the lower values of PI variability at the same BRS with a decrease in SBP variability. The primary SBP variability increased during exercise. The interrelationship among the variability of SBP, PI and BRS was identical at rest and during exercise. During exercise, the increasing primary variability in SBP due to sympathetic activation was present.
