Vascular resistance arm of the baroreflex: methodology and comparison with the cardiac chronotropic arm
Copyright policy )Vascular resistance arm of the baroreflex: methodology and comparison with the cardiac chronotropic arm
Baroreflex response consists of several arms, but the cardiac chronotropic arm (blood pressure changes evoking heart rate response) is usually analyzed. This study introduces a method to assess the vascular baroreflex arm with the continuous noninvasive measurement of peripheral vascular resistance as an output considering causality in the interaction between oscillations and slower dynamics of vascular tone changes. We conclude that although vascular baroreflex arm involvement becomes dominant during orthostasis, gain of this interaction is relatively stable.
