| Description | The aim of this paper was the study of a development of baroreflex sensitivity (BRS in ms/mmHg: BRSf) in children and adolescenis and of an interrelationship between BRS (BRSf) and variability in pulse intervals (PI) and systolic blood pressure /SBP) at the frewuency of 0,1Hz. It was shown that PI variability positively correlatec with BRS and had a dampening effext on SBR variability. The additional effect of a primary variability of SBP on this relationship was found. The interrelationship between BRS and the variability in SBPund PI ot the frewuency of 0,1 Hz was age independent, but it was age-dependent for BRSf and variability in SBP and PI. This difference might be linked to the nean PI. |
