To simulate the prehypertensive SS baroreceptor
systemic phenotype of partial baroreceptor
impairment (10,13), a chronic bilateral aortic denervation was performed instead of a chronic bilateral carotid sinus denervation, because the destruction of chemoreceptors during the carotid sinus denervation (22,23) in a species like the rat, which lacks functional aortic body chemoreceptors (25), causes chronic hypoventilation with consequent chronic systemic hypoxia, which in turn has the chronic effect of lowering blood pressure (23).
In the older picture, the baroreceptor
response is blunted with age, perhaps as a result of stiffer arteries.
Central nitric oxide attenuates the baroreceptor
reflex in conscious rabbits.
The value of heart rate variability and baroreceptor
sensitivity, markers of autonomic nervous function, in predicting SCD is similarly unknown.
As a chemoreceptor, it is distinct from the carotid sinus, which is a baroreceptor
Maintaining SABP involves compensatory mechanisms such as baroreceptor
reflexes, vasoconstriction, and the pumping effect of the skeleton muscles and the lungs that help facilitate venous return to the heart.
Attenuation of the baroreceptor
reflex by general anesthetic agent in the normotensive rat.
One, CPAP may reduce sympathetic activation by causing a resetting of baroreceptor
The mechanism by which n-3 FA influences HRV is thought to involve the modulation of adrenergic-mediated baroreceptor
activity or enhancement of vagal activity (Mozaffarian et al.
reflexes cannot regulate blood pressure in the long term, because receptor firing rates adapt to prolonged changes in blood pressure.
The researchers found that nitric oxide is a potent regulator of BDNF in baroreceptor
The concomitant use atropine with associated tachycardia can exacerbate the pressor effects of phenylephrine (and prevent appropriate baroreceptor
induced bradycardia), especially in infants.
