Abstract

The authors have examined the question asked in the title by studying: the carotid baroreceptor reflex in man with a variable-pressure neck chamber; the carotid baroreceptor reflex in conscious rabbits with a variable-pressure capsule around the carotid bifurcation; and the baroreceptor-heart rate reflex. At rest, the association between the sensitivities of the carotid baroreceptor-blood pressure and -heart rate reflexes, and of these with the baroreceptor-heart rate reflex, is weak. Exercise causes dissociation between control of blood pressure and heart rate. In hypertension, depression of the baroreceptor-heart rate reflex does not reflect the altered characteristics of the carotid sinus-blood pressure reflex.
