What changes are expected when carotid sinus is digitally compressed?
Carotid sinus pressure will produce increased baroreceptor discharge inhibits the tonic discharge of the vasoconstrictor nerves and excites the vagal innervation of the hea, producing vasodilation, venodilation, a drop in blood pressure, bradycardia, and a decrease in cardiac output.
