I'm 26 years old. I'm a smoker. I'm trying to quit. My problem is rapid heart beat after I eat or whenever I get up too fast or do anything pretty much.. When I stand up sometimes my heart races to where I have to sit down or else it feels like my heart will explode. My other problem is that my heart races after I eat. I suffer from skipped heart beats as well. I'm just so scared my heart is going to stop soon... I feel like my chest just always feels strange Is 26 old enough to have heart failure???
