Key result
Changing the relative timing between aortic and carotid sinus baroreceptor activity caused minimal to no variations in blood pressure or heart rate in anesthetized rabbits and dogs.
Why the study?
Does changing the relative timing of aortic and carotid sinus baroreceptor activity affect blood pressure and heart rate in anesthetized rabbits and dogs?

Variations in pulse-wave velocity are unlikely to play a significant role in acute cardiovascular control based on baroreceptor timing experiments in animal models.

Minimal impact of baroreceptor timing on BP/HR in anesthetized animals; leaves open pulse-wave velocity effects on human cardiovascular control.
Katona et al. (1975) studied this question. Changing the relative timing between aortic and carotid sinus baroreceptor activity was evaluated on Variations of blood pressure or heart rate. Changing the relative timing between aortic and carotid sinus baroreceptor activity caused minimal to no variations in blood pressure or heart rate in anesthetized rabbits and dogs.
