I had an ASD repair when i was 16
in 1991. Ihave been on dozens of heart meds since. Ive been in and out of the hospital for atrial flutter, tachicardia, bradycardia, palpitations, and so on. I have had every test done there is. Finally at the age of 33 i had radio ablation done. This has helped alot but i still have eptopic beats and some flutters. You need to see a electrophsiologist and they can do something for you. I was also told i would need a pacemaker in the future....
