Bain- bridge reflex -
True reflex
Not by activation of stretch reflex
On injecting saline into the blood vessel of an anaesthetised animal HR increases if previously it was LOW
Vagus mediated reflex
Explains y there is increased HR in MI
In MI the reflex is mediated due to release of seratonin from damaged tissue in the vessels of LEFT ventricle
Seratonin released into vessels of Atria or right ventricle does not initiate the reflex
