What should be a normal heart rate? I'm 22 and my heart rate is 100 beats per minute. This is normal?

This is not entirely normal. After all, a normal heart rate is 60-90 beats

I think this is not the norm

A normal heart rate is 75 beats per minute for your age. But if you are worried, then such a pulse can be.

depends fromperson and his physical activity

Your resting heart rate should be no more than 110 beats per minute (if you are overweight) and 90-100 beats per minute (maximum) if you are not overweight. That's what my doctor used to say.

Hey,
Children (6 to15) 70 – 100 beats per minute.
Adults (18&over) 60 – 100 beats per minute.
