Mechanism of Reflex Bradycardia which Follows Sudden Closure of an Arteriovenous Fistula. ∗

Abstract

Conclusions

1. The receptors for the reflex bradycardia which follows sudden closure of an arteriovenous fistula, are the pressoreceptors of the arterial side of the circulation, the carotid sinuses and aortic arch. 2. In some animals the carotid sinuses are the predominant arterial pressoreceptors, and in others the aortic arch is predominant.
