naturally fast heartrate with a HRM

I have a naturally fast heart rate... My rate when I'm just standing still doing nothing can range from 90 to 125 bpm, so as I work out it gets anywhere up to 175-180 depending on how hard I am pushing.
i have been using my heart rate monitor while exercising and am concerned that it isn't accurate in how many calories I have burned. according to my understanding, the faster your heart rate, the more calories burned. I'm concerned that my body takes a higher heart rate to burn the same amount of calories as someone with an average heart rate.. which would mean that the HRM is inaccurate for my body, which means I have no clue how many calories I am really burning. Does anyone have any insight into this issue?

p.s. My doctors have all noticed the fast heart rate but don't seem to be concerned.

    I have tachycardia (fast heart rate).

    I take a beta-blocker called Propranonol for it. It slows down my heart rate.

    My RHR is anywhere from 100-170. Obviously when I am above 125/130, I am in the hospital.

    If you are overweight, your RHR is going to be faster because your heart is having to work harder.

    As long as you aren't having any symptoms like fainting, dizziness, etc., I wouldn't be too concerned.
  • Tachycardia is a RhR of 100bpm or more. It is a sign of hypertension, but will normally drop off with a good diet and lots of aerobic exercise. Ellipticals are good for getting the valves to close off when on a "coasting" portion. You should talk to your doctor though.

    Kelly, what is your blood pressure?

    The HRM will give you an inflated burn. The calorie estimation formulas are based on averages, so an average heart rate. If you have a higher than average HR, it will not account for that. It is a "dumb" instrument. It cannot distinguish whether you HR is elevated due to cardio or something else. It will assume the higher HR is due to cardio exercise and calculate calories based on that.

    Keep in mind HR is not directly related to calories burned. It is a very common misconception here. Yes, often when our HR is elevated, we are burning extra calories, but that does not mean that HR= calories burned. We are not burning extra calories when our HR is elevated due to a scary movie. There is a relationship between HR and VO2 max (again based on averages) during steady state cardio (which is why HRMs are only accurate for steady state cardio) that allows for calorie estimation.

    Here is a thread that is pretty helpful in explaining how they work

    my blood pressure is always in the lower range of "good" blood pressure... my doctors are always impressed... i can't remember what it is off hand though.

    but the thing is even when i was younger and wasn't over weight my heart rate was still faster than average.. i didn't become over weight until i hit puberty, and even still i wouldn't say i am very over weight.. i only need to lose 10-15 lbs to be at a good bmi... all of my doctors are aware of the fact that it is fast and none of them have voiced any concerns about it, i've even seen a cardiologist in the past (for a different reason) and he didn't say anything

    90-125 bpm isn't TOO fast. And since your doctor is aware of it and hasn't done further testing to determine the cause, I wouldn't worry. Some people just have a naturally faster heart rate.

    If you are out of shape, this can also contribute to a faster heart rate. Anxiety also makes heart rate increase.

    Do you have any other symptoms besides a fast heart rate?
