| Description | V jazyce výsledku Baroreflex sensitivity was evaluated in 20 obese children and adolescents in comparison with 20 age-and sex-matched nonobese subjects. All subjects were examined in the supine position over a period of 50 min. Systolic blood pressure (SBP) and RR intervals were monitored continuously. Baroreflex sensitivity (BRS) was assessed by crossspectral analysis of SBP and RR interval oscillations at 0.1 Hz in 3 time intervals of 3 min each. The BRS index was significantly lower in obese children and adolescents than in the nonobese control group (p = 0.002). Significant changes in the BRS index over time (p = 0.004) were found only in nonobese subjects. |
