[The effect of the initial (controlled) tonus of the arterial vessels on the correlation of arterial pressure and cardiac output during a pressor reaction to a rapid blood volume increase in rats].
A considerable decrease in pressor responses to polyglykine at an elevated arterial tone and constant increase of cardiac output occurred in anesthetised rats. Vascular and cardiac mechanisms of the interrelationship are discussed.
