So your on a heart medicine then to correct the arrythmia?
My 2 cents..
Not to say what's already been said, but you should definatly push your doctor about this if it's something your worried about.
I had the heart flutter for a long time, was off an on. I wasn't honestly to worried about it because I've had it as long as I can remember.
A few years ago a developed gallstones and started having gallbladders attacks, but of course at first I didn't realize that was what it is.
When I finally broke down one night and went to the ER then thought I was having a heart attack and gave me an EKG and discovered I had an arrythmia.
The gallbladder thing wasn't picked up until another ER visit with another gallbladder attack =/
