Six rabbits were exercised on a moving belt at 13 m/min for 60's. Heart rate (HR), mean arterial pressure (MAP), cardiac index (CI), and systemic vascular resistance index (SVRI) were measured. Exercise was done under the following four permutations of input from baroreceptors (B) and cardiac receptors (C): BC, both inputs present; B, only baroreceptor input (intrapericardial procaine); C, only cardiac receptor input (surgical barodenervation); 0, both inputs deleted. The reflex effects on SVRI… CONTINUE READING
