Comparative Study[The dependence of shifts in arterial pressure and cardiac output during alpha-adrenoreceptor stimulation on the initial (controlled) tonus of arterial vessels in rats].
A significant decrease in arterial pressure and total peripheral resistance occurred following elevation of the initial blood pressure to 160 mm Hg with mesathone in anesthetised rats. The increase in the cardiac output remaining unchanged. Vascular and cardiac mechanisms of the revealed relationships are discussed.
