Bezold–Jarisch reflex

The Bezold–Jarisch reflex (also called the Bezold reflex, the Jarisch-Bezold reflex or Von Bezold–Jarisch reflex) 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 low resting heart rate) in response to noxious stimuli detected in the cardiac ventricles. The reflex is named after Albert von Bezold and Adolf Jarisch Junior. The significance of the discovery is that it was the first recognition of a chemical (non-mechanical) reflex.
