Abstract

V originále

The aim of the present study was to determine the interrelationship among the baroreflex sensitivity (BRS), the variability in systolic blood pressure (SBP) and pulse intervals (PI) at the frequency of 0.1 Hz in hypertensive adolescents.Adlescents were divided into groups according to the spectral power at the frequency of 0.1 Hz. The following limits of power were used: high C hSBP>100, hPI>12500; middle 100>mSBP>55, 12500>mPI>5400; low C lSBP<55, lPI<5400. We analysed the relationships between the groups A(hSBP, hPI), B(mSBP, hPI), C(lSBP, hPI), D(hSBP, mPI), E (mSBP, mPI), F(lSBP, mPI), G(hSBP, lPI), H(mSBP, lPI), I(lSBP, lPI).The highest number of controls is in groups A, E, I (together 40%), and the lowest number is in groups C (8%) and G (6%). The hypertensives are concentrated into the triplet subgroups with high SBP variability (88%); the maximum hypertensives were in subgroup A; any hypertensive adolescent was in groups C, F, H, I (0%).

In Czech

Cílem práce bylo stanovit rozdíly ve vztahu mezi baroreflexní senzitivitou (BRS), variabilitou systolického krevního tlaku (varSTK) a tepových intervalů (varTI)u dospívajících osob s hypertenzí. Nalezli jsme signifikantně vysoké zastoupení dospívajících osob s hypertenzí v oblasti s vysokou variabilitou krevního tlaku. Vysoká variabilita tlaku jako známka zvýšené sympatické vasomotorické aktivity může být rizikovýcm faktorem pro hypertenzi.
