What changes are expected when carotid sinus is digitally compressed?

A
Hea rate decreases, peripheral resistance increases
B
Hea rate and peripheral resistance decreases
C
Peripheral resistance and contractility decreases
D
Peripheral resistance and contractility increases
High-Yield Explanation
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.
