The reflex bradycardia produced by a transient phenylephrine-induced rise of arterial
pressure was investigated in man during rest and supine exercise, before and after …

Based on results of, for example, local anesthesia of the carotid sinuses (26, 32) and
injection of sympatholytic drugs (18), the baroreflex has long been known to be active also in …

In patients with congestive heart failure (CHF), overactivity of the sympathetic nervous
system may be accompanied by an impairment of the baroreflex control mechanism. To …

Although human baroreflexes are known to exert a powerful physiological control on heart
rate, little information exists on the physiological control they exert on the atrioventricular …

Baroreceptor sensitivity, reflected by the slope of the linear regression of the
electrocardiographic RR interval on the rise of systolic blood pressure after injection of …

1. A method is described for altering the pressure across the wall of the carotid sinus in
conscious rabbits by enclosing the carotid bifurcation in a rigid, fluid‐filled capsule. The …

The effect of the intravenous (iv) shortacting anesthetic propofol on baroreflex control of
heart rate (HR) was examined in normotensive rats. Propofol was infused at a fixed rate of 9 …

Many vasodilators have been tried as antianginal agents, but the reflex increase in
sympathetic tone produced by these drugs necessitate their use with caution in patients with …

The baroreceptor-heart rate reflex in human is impaired 2 days after a myocardial infarction
but it improves 10 days after the acute coronary event. This study investigated whether (1) …

We studied the control of arterial pressure by the carotid sinus baroreceptors in 35
hypertensive humans, using a variable pressure neck chamber to alter carotid sinus …
