心跳問題~好似好快咁

Since there are several factors affecting the heart beats such as stress, emotion, or even temperature. It is not true to observe whether 一分鐘跳90下左右..is normal or not.

When did the data collect, in cold day or hot day?
When the day is cold, more energy is required for our body to produce ATP and hence faster heart beat.

Did you feel stress or scared during the measurement?
Besides, for such your age, you are at the stage of development. A higher metabolic rate is required to support your growth. Hence don't think there are some problem first.

Take the following steps
(1)measure the heart beat when you are at rest such as wake-up time早晨起身時.
(2)record them only when you are at rest, not scared or even feeling stress. Then compare them. If for several weeks recording, the values are still high (actually,90下左右不是太高), seek for medical advice.

I hope my information can help you.

從生理學上，心跳指心臟的跳動，正常人平靜時每分鐘60到90次，運動時心跳會加速，心肺功能較好的運動員會比正常人的心跳要慢。。
