Abstract

V originále

The correlation between baroreflex sensitivity (BRS), the component of spectrum at the frequency of 0.1 Hz of inter-beat intervals (IBI), and systolic blood pressure variability (SBP) at rest and during exercise was studied. Blood pressure of 38 healthy subjects(aged 21-22 years) was recorded beat-to beat at rest (3min), during exercise (0.5 W/kg of body weight, 9 min) and at rest (6min) after exercise. Spectral analysis of recording of SBP and IBI was performed. Four techniques for continuous determination of BRS were used: seguence method, modified complex demodulation, alpha index technique and LP model technique. BRS at rest damps blood pressure variability at the frequency of 0.1 Hz by changes in IBI. During exercise, when BRS is low, the changes of IBI are not high enough to damp blood pressure variability.
