Abstract

V originále

A causal interrelationship between the 0.1 Hz variability of systolic blood pressure (SBP) and pulse intervals (PI), and baroreflex sensitivity (BRS) was shown. During exercise, the increasing primary variability in SBP due to sympathetic activation is present, but it does not change the relationship between variability in PI and BRS, which is mediated by parasympathetic nerves.

In Czech

Kauzální vztah mezi variabilitou při 0.1 Hz v systolickém tlaku, tepových intervalech (PI) a citliostí baroreflexu (BRS) byl ukázán. Během cvičení roste primární variabilita v systolickém krevním tlaku, ale nemění se vztah mezi PI a BRS, které jsou závislé na aktivitě parasympatických nervů.
