... and peripheral resistance. 2. Blood pressure remained low during the first year after withdrawal in spite of the fact that the heart rate increased within the first few days. 3. Cardiac output was found to increase during the first year after withdrawal, although total peripheral resistance was essentially...

... days. 2. The initial 5% decrease of body weight was associated with decrements of arterial pressure and total peripheral resistance of 15 and 35% respectively, whereas cardiac output had risen by 25%. After a further decrease in body weight by 5%, arterial pressure was lowered another 15% without...

... excitation. An elevated total peripheral vascular resistance at rest and a greater fall in peripheral resistance with α-adrenoreceptor blockade (intravenous phentolamine) suggested the existence of a neurogenic increase in arteriolar resistance. 3. Blood pressure was normalized by ‘total’ autonomic blockade...

... the fall in blood pressure that immediately followed injection of converting-enzyme inhibitor. 2. Chronically salt-deprived rats had normal arterial pressure, cardiac output and total peripheral resistance before inhibition. However, inhibiting the formation of angiotensin II caused marked decreases...
