INEXCITABILITY OF THE BAINBRIDGE, MCDOWALL AND HARRISON REFLEXES

Abstract

The Bainbri ge, McDowall and Harrison reflexes were not elicited by central venous hypertension, hypervolemia or tachyrrhea in 32 closed-chested intact, carotid-sinus baroreceptors denervated and vagotomized dogs. Localized caval and right atrial distention and perfusion did not induce reflex cardiac acceleration. The heart accommodated to increased filling by augmenting stroke volume. Arterial pressure was changed only in relation to cardiac output. Respiration was not affected. (Author)
