I remember reading somewhere that if the underlying problem of the enlarged heart is treated in time, it can be reversed. If it goes on too long it can be permanent.
I would take Vienna and ChatterAlly's advice and see a cardiologist. Sooner better than later.
Best wishes
Seeing a cardiologist is your best decison now. Could be a benign arrhythmia, but you never know. Have some tests and see what comes of that. Better to take it seriously at first. Take care, Ally
You should see a cardiogolist,listen to your family. Better to be safe!
Good luck to you!
