We did a heart rate lab in biology today where we monitored our own heart rate.  The results shocked me.  I have been on a lot of steroid based meds for my asthma lately, and my resting heart rate was about 80, and after only taking a few steps(like 4 or 5) it jumped to 200 in like a second.  I can feel that I have an irregular heart beat/palpitations and I feel nauseous and dizzy all the time.  I knew the medicine was messing with my heart, but how serious is this?  Should I go to my doctor?P.S.  My resting heart rate just a few months ago was 50-60.
