Overview
Bezold-Jarisch reflex is the occurrence of bradycardia and hypotension through a pathway involving cardiac receptors,medullary centers and vagal afferent nerves.[1] It results from cardiovascular depressor reflex involving a marked increase in vagal efferent discharge to the heart, elicited by stimulation of mechanoreceptors, primarily in theleft ventricle. This leads to bradycardia and dilatation of the peripheral blood vessels with resulting lowering of the blood pressure. [2] [3] [4] Bezold-Jarisch reflex is responsible for 61% of bradyarrhythmia that occur within the first 60 minutes of inferoposterior myocardial infarction.[5] In addition, it is considered a good prognostic indicator of successful early reperfusion and coronary artery patency in the setting of thrombolysis after inferoposterior MI.
