Re: whats the point of an ecg?
I very much doubt your troponin stays at a fixed level your whole life. And if it was only released if your heart was damaged then it should be 0 constantly and not within a range of numbers. Therefore if yours is within normal range yet slightly elevated and you have a normal ecg (which would be doing all sorts of crazy things very obviously if there was something wrong with your heart) it is elevated due to other things, such as exercise. It makes sense, and the doctor seems very certain you're ok.
