Sudden intravenous injections of small amounts of angiotensin or phenylephrine were given
to 30 subjects to produce modest, brief increases in directly measured systemic arterial …

In adult conscious sheep the pressor actions of infused angiotensin II were prevented by the
concomitant intravenous infusions of sodium nitroprusside. The effect of such intravenous …

Angiotensin II is a potent vasoconstrictor and has profound effects on autonomic neural
mechanisms in experimental animals. Human carotid baroreflex control of arterial pressure …

Both arterial baroreceptor reflexes and cardiopulmonary reflexes are modified in human
hypertension. The arterial baroreceptor reflex regulation of heart rate, when tested by both …

Cardiovascular reflexes that are mediated by receptors in the heart and blood vessels
control a variety of important hemodynamic and humoral functions. The action of these …

Two methods were used for altering blood pressure in conscious rabbits by up to±30 mmHg
from the resting level in order to characterize the barorecep‐tor‐heart rate reflex. These …

The mechanism of the attenuated arterial baroreceptor control of heart rate in heart failure
was studied in 18 unanesthetized dogs after the development of chronic right-heart failure …

Arterial blood pressures were measured simultaneously in the thoracic and abdominal
aortas in the same conscious rats. Intravenous administration of sodium nitroprusside …

1. Beat‐by‐beat changes in cardiac performance in response to arterial baroreceptor
stimulation induced by phenylephrine were evaluated by pulsed‐wave aortic Doppler …

The control of heart rate by the arterial baroreceptors and the evidence that these reflexes
are impaired in people with raised arterial pressure are reviewed. The results with the …
