Heart beat raising extremely fast

[KGummert]

I'm almost 21, i'm about 5'5 somewhere around 133 pounds. For the last couple of years i've noticed that the moment i step onto a treadmill or anything of the sort within the first 5-10 minutes of doing any movement my heart is right up in the 200's. i've asked a couple people, one said i needed to strengthen my heart, another said to see a dr. so i'm just wondering if anyone else has this or what they think it is or what i should do. Thnx =)

You should be check by a Doctor, maybe you're having Tackys, which can be treated or cured.  I have had this rapid heart all my life and now there is a procedure to stop them.

Hmm.  While it's just a guide for exercising, a person's maximum heart rate is calculated as 220-(your age), which would make yours 200bpm.  And that's not carved in stone, it's just a guide.

Is it possible that you push yourself so hard that you can get your rate up to 200 that fast?  Could be.  I know as recently as a decade ago (when I was 30) I would be able to pretty easily get my heart rate up into the 190's, and never thought anything of it.  It was just a number to me; I didn't know I wasn't supposed to be doing that, and I felt fine the whole time.

So it's hard to give you a good answer.  What's your resting heart rate, usually?
