what is mechanism of isoprenaline in tilt table test

[@JohnsonFrancisMBBSMDDM]

Good question. Isoprenaline increases the force of myocardial contraction. Vigorous contraction stimulates mechanoreceptors and paradoxically leads to withdrawal of sympathetic drive and increasing parasympathetic output. This is akin to the Bezold-Jarisch reflex (th-cam.com/video/GEZx-AFr0wo/w-d-xo.html) Ref: www.ncbi.nlm.nih.gov/pmc/articles/PMC5319004/
