Abstract

ORIG CZ

V originále

BACKGROUND: We postulated that the phase shift between blood pressure and heart rate fluctuation near the frequency of 0.10 Hz might be useful in assessing autonomic circulatory control. CONCLUSIONS: The frequency of 0.10 Hz represents a useful and potentially important one for controlled breathing, at which differences in blood pressure-RR interactions become evident. These interactions, whether computed as a variability of phase to define stability of the blood pressure-heart rate interaction or defined as the baroreflex sensitivity to define the gain in heart rate response to blood pressure changes, are significantly different in patients at risk for sudden arrhythmic death.

In Czech

Fázový posun variability krevního tlaku a tepových intervalů může být použit pro hodnocení dysfunkce autonomního nervového systému.
