What is Vagal overdrive??

Question

Hi there, im a paramedic student studying in Coventry, whilst studying my drugs i see that atropine reverses the effects of vagal overdrive, im aware that the vagus nerve (X) controls many important parasympothetic functions, and could probably guess what vagal overdrive is, but I would like to know for sure. I cant find anything on the internet or in my anatomy and physiology books. Thanks.

Answer 1

Have you tried looking under vasovagal overdrive? Isn't it to do with when vagal activity is decreased and causes bradycardia? Atropine acts to inhibit that...  Hahaha, i'm not a med student that's for sure. I'm a vet tech who would much rather have gone and finished her vet degree and constantly trying to diagnose things! I hate not knowing the whys of medicine!!!
