Musse -- you are on the no more panic forum, aren't you?  Me, too!  I wrote this there, but just in case you check here first:  If this is really bothering you, please see your doctor for reassurance.  It has happened to me on several occasions when I have been really stressed -- it's like the first flutter thing happens when I am off guard and then I panic and then I get subsequent palpitations and they seem to get worse and worse.  I actually went to the ER for another reason, but on my way I experienced this and my EKG was normal.  I think it's just one of those glitches that stress and anxiety cause.  But, again, do get it checked out.  You'll feel much better once you do.  I don't forsee a pacemaker in your immediate future.    Hugs, Jen ~

Musse -- of course you can go to various forums for help.  And, you weren't wasting my time.  I was on NMP last night and saw your post and I thought, This looks familiar!     I hope you are feeling better today -- good news is you survived your ordeal, which I really believe if it was something serious, you'd be in the hospital by now. I always try to look at things this way -- your body will let you know if something really bad is happening.  I read once if something was seriously wrong, you would be running TO help, instead of AWAY from it and wanting to write looking for answers and so forth.  Now you can look into getting help and reassurance for it.     My best to you.  Please keep me posted, ok?
