fluttering heartbeat

I have been recently experiencing heart flutters which I used to get a few years ago. I had been tested back then and all tests were normal. (ekg, electrocardiogram, blood tests, halter monitor and event recorder which of course never picked up any palpitations). Just wondering what could be causing them again.

There are a lot of reasons a heart can flutter. Some include...stress, foods and drinks, including...caffeine, alcohol, msg, chocolate, fried foods...and some medical conditions...thyroid problems, GERD, etc. Any time you have new symptoms or symptoms you haven't had in a while, you should let your doctor know.
