<prompt> What changes are expected when carotid sinus is digitally compressed?Hea rate decreases, peripheral resistance increasesHea rate and peripheral resistance decreasesPeripheral resistance and contractility decreasesPeripheral resistance and contractility increases  <response>: 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.
