A Cardiac Factor in Hypertensive Responses
DELINEATION BY TRANSPLANTATION OF THE HEART
Patterns of blood pressure response to direct and reflex activation of the central nervous system were compared in normal dogs and in dogs after cardiac autotransplantation. Interventions which regularly result in elevated systemic blood pressure in the normal, anesthetized dog may produce attenuated pressor reactions, or even depressor reactions, in the dog with a cardiac autotransplant. The differences in response patterns indicate a significant contribution by the heart to the pressor response of the intact dog.
