Palpitations can be caused by GERD and of course a host of other conditions as well. I know when my GERD is acting up, which is most of the time, the palps are more active or maybe more noticed. I hate this, it sucks and nothing so far is giving me ultimate relief. I'm now on my 4th different drug for this and if this doesn't do it, surgery is next. So we all agree, this sucks!!!! Hang in there!
