Title: calcium ionz?
Post by lmg83brown on Feb 4^th, 2012, 3:25pm

Hi, I was wondering if there was a difference between vagus nerve ectopics and adrenaline induced ectopics. I read that adrenaline causes them via calcium ionz. The adrenaline's effect on the heart causes calcium to build on the mucsle causing a pvc. Is this accurate? It also stated that large quantities of adrenaline can be harmful(calcium overload). Please explain how ectopics from adrenaline whether it be from exercise or anxiety are caused. I understand that the vagus nerve is the sole cause in benign ectopics, but texts state that adrenaline causes them to via calcium ionz overload.
