Abstract

V originále

Correlation between baroreflex sensitivity (BRS) and the component of spectrum and a frequency of 0.1 Hz of inter-beat intervals (IBI) and systolic blood pressure (SBP) was studied in 38 subjects at rest and during exercise. BRS was determined by 5 techniques: sequence method, complex demodulation, alpha index, LP model, and wavelet technique. BRS damps blood pressure variability at the frequency of 0.1 Hz by changes by IBI. During exercise when BRS is low changes of IBI are not high enough to damp blood pressure variability.

In Czech

Korelace mezi citlivostí baroreflexu (BRS) a spektrem při 0.1 Hz v tepových intervalech (IBI), a krevním tlaku (SBP) byla studována u 38 osob. BRS bylo stanoveno 5 metodami: sekvenční, komplexní demodulací, alfan indexem, LP modelem a vlnkovou metodou. BRS snižuje variabilitu při 0.1 Hz změnami v IBI. Během cvičení, kdy je BRS nízká, nejsou změny IBI dostatečné k potlačení variability v tlaku.
