The aim of the study was to investigate the development of noninvasively determined baroreflex sensitivity in age between 11 to 18 years. Continuous 5 min blood pressure readings were recorded in 332 healthy subjects. Beat-to-beat values of inter beat intervals (IBI), systolic blood pressures (SBP) were measured. Baroreflex sensitivity in ms/mmHg (BRS) and in mHz/mmHg (BRSf) was determined by spectral analysis. BRS did not correlate with age, BRSf significantly decrease with age (p<0.001). BRS correlated with mean IBI (p<0.001), but BRSf was IBI-independent. Multiregression analysis showed significant decrease of BRS with age after standardization to IBI. The limits of BRS were estimated for the whole group: 5th percentile - 3.9 ms/mmHg; 50th - 9.1; 95th - 18.9. BRS was unchanged in particular age groups, but it was dependent on IBI. Standardization of BRS on IBI disclosed its decrease with age. BRSf is IBI-independent and better reflects the development of baroreflex sensitivity with age.
