I WALKED up the one flight of stairs at my school. Instantly felt my heart racing so I took my pulse. I was trying really hard to exercise yesterday and after 15 minutes got right around this heart rate. Should I be concerned?
Mine is between 110-120 resting but I have tachycardia and am on a beta blocker for it. You may way to start checking your heart rate and jotting it down. If it stays like that then you may want to see your doctor. Any number of things can cause it.
