Bezold–Jarisch reflex - Wikipedia
The Bezold–Jarisch reflex (also called the Bezold reflex, the Jarisch-Bezold reflex or Von Bezold–Jarisch reflex[1]) involves a variety of cardiovascular and neurological processes which cause hypopnea (excessively shallow breathing or an abnormally low respiratory rate), hypotension (abnormally low blood pressure) and bradycardia (abnormally lo...

May 20, 2022 · cardiodepressor Bezold-Jarisch reflex (BJR) acts as a protective reflex to vasodilate the coronary arteries in the setting of inferoposterior infarction associated with coronary vasospasm. The BJR is thought to be responsible for up to 60% of bradyarrhythmia occurring within the first 60 minutes of infarction and for the occurrence of AV nodal ...
Clinical Relevance of the Bezold–Jarisch Reflex
Classic activation of the Bezold–Jarisch reflex (BJR) by veratrum alkaloids. Originally characterized as a pharmacologic reflex, the BJR is activated by a variety of veratrum alkaloids. BJR activation leads to decreased vasomotor output, bradycardia, and hypotension.
Bezold-Jarisch Reflex - an overview | ScienceDirect Topics
Bezold-Jarisch reflex is cardiovascular decompressor reflex that is activated in response to myocardial ischemia, spinal anesthesia and is characterized by deleterious effects including SA node blockade, sudden bradycardia, marked hypotension, reduced inotropy and coronary vasodilation due to activation of TRPV 1 channels.
Vagal sensory neurons mediate the Bezold–Jarisch reflex and …
Nov 1, 2023 · The Bezold–Jarisch reflex (BJR), first described2,3 in 1867, is a cardioinhibitory reflex that is speculated to be mediated by vagal sensory neurons (VSNs) that also triggers syncope.
The Bezold-Jarisch reflex revisited: Clinical implications of ...
The concept of depressor reflexes originating in the heart was introduced by von Bezold in 1867 and was later revived by Jarisch. The Bezold-Jarisch reflex originates in cardiac sensory receptors with nonmyelinated vagal afferent pathways.

The Bezold-Jarisch reflex is characterized by the triad of bradycardia, hypotension, and peripheral vasodilation. It occurs most commonly after reperfusion during an inferior or inferior-posterior MI.
