Flutters under breast bones

Has anyone experienced chest flutters. It is under and between my breast bones right directly under. It was sharp pain under the left especially when it was evident for gas and then this flutter keeps happening, at some points feels like intestinal gas but so high up. I am mostly worried about heart issues because my aunt was once diagnosed with gull bladder and it was a heart attack.

As far as I know when I've looked into heart troubles on one of my panic drives, sharp pain doesn't mean anything. Not sure what to tell you is bad incase you start imagining you have it instead if you are anything like me- but as far as I know a deep, dull pain in the centre (not left) of chest is the worrying kind.

thank you
