For a few years now I have been getting extremely fast heart palpitations that last anywhere between 2 minutes to 45 minutes. I always thought that they were brought on by my anxiety (although I was never feeling particularly anxious at the time). However lately I've noticed that I get them when I bob down or lift things up over my head.
Once I lifted something up and it felt as if my heart stopped, I was seeing stars and felt very hot as if I was about to faint.
I'm a teenage girl, not overweight and not terribly unfit either. I know that heart palpitations are considered to be normal sometimes but should I be getting this checked out?
