I've been having palpitations since last Tuesday and I'm getting worried about them now :(

They last about a second (or less) but I've been having them throughout the days. It's driving me mad, I could be sitting around not doing anything and I'll still have them. Normally they don't bother me but they've been going on for quite a while now. They're pretty consistent. I get a few every hour. I'm sure I've probably missed some where I haven't been paying attention.

I'm not sure if I should get checked out or not. I don't want to become obsessed!
