This historical case report describes Branham's sign, demonstrating that compression of the artery proximal to an arteriovenous fistula causes profound reflex bradycardia.
Answers are grounded in this paper and cite their sources.
May support Branham sign recognition in arteriovenous fistulas; leaves open prospective validation in modern cohorts.
