I'm 16 and my resting heart rate today has been between 100-140 bpm all day and im so out of breath, please help
I see this is your first post. Did this happen before? Did you get checked out by a doctor now or in the past? You are only 16, did you say something to a parent? What is normal for you? Are you athletic or a couch potato? Do you suffer from anxiety and panic attacks?
