I have the occasional fluttering feeling under my breastbone as well,,,,,does not happen constantly, may happen a few times a day for a few days and then may not happen for a while - I have no paid either.....it just feels very weird. I was diagnosed with acid reflex about a year ago, and now take a daily prilosec pill....I was wondering if this might be causing the fluttering? It is a very disconcerting feeling,,,and if it keeps up, I may get my doctor to check it out.....
Atrial flutter just happens sometimes. Good news, it is not life threatening. Bad news, if you feel the symptoms it can get pretty uncomfortable (from my own experience)
There are plenty of ways of treating flutter : medications and procedures. And if your heart is in good condition which I assume it is you will get rid of the flutter soon
