Should my heart beat this fast? - average bmi in other countries

I am 17 years old
5 feet 4 inches
£ 117
Body mass index 120

I consider myself in good shape. I exercise regularly and was a member of my school track team and cross country. But every time he does it, when a 5k, training, elliptical, or static, my heart was on average 187-197 beats per minute after 5 minutes of exercise. This continues throughout the entire work. I know that this number is a maximum number of decent, but it is a constant. Is this normal?
