Well, i had an ECG a year ago as I wanted to get it checked out because of some medication i was on. Well, it turned out completey normal. But, i am (without knowing why) very paranoid and worried that i am going to have a heart attack or die in my sleep from heart failure. Thing is, i feel something may have developed during the year, is it possible for something serious or life threatening to occur during a year or less? a lot of people have said its not really that possible or very rare, but i need to ask all of your opinions. i am 16 years old, and i am not writing this as a joke, i am just very worried and im not sure why. thank you.

What makes you so concerned about your heart? DO you have any strange symptoms or unusual feelings? And what was the deal with checking out your ecg because of your medication? Obviously you have some real concerns here, could you please say why?
