你的心跳是不是太快了呢

如果只是你坐在那里，什么都没干，而心跳却超过了100跳每分钟，那么你的身体可能存在着隐患哦，听听专家怎么说。

So how was it, Doctor? Was it alright? Good, good. OK. I have my pulse checked cause Jim from Taxas says his pulse is fast, really fast and he'd like to know if he should worry about it. Is a fast pulse an indication of anything specific?

"Well you know the normal pulse rate is said to be between 80 and 100. Anything more rapid than that is abnormal. Well there are things you know that cause a fast pulse, you get excited, you are fearful, you are anxious, you are stressed, you have fever. Those are all things that give you a fast pulse. But having a fast pulse all the time when you are just sitting around is not right.

The first thing I suggest you have checked is your thyroid. An over active thyroid will give you a rapid pulse. There are other causes and you have to determine whether the rapidity, the speed of the pulse is associated with an irregularity. I mean is the pulse rapid but regular bong bong bong? Or is it irregular bong bong bongbongbong bong, that would be atrial fibrillation. So the first thing you have to determine is if your pulse is regular.

Now I'm assuming that your pulse is regular. Anaemia will cause it. If your thyroid is normal, have your blood checked because anaemia causes a rapid heart rate. In women there is a very common abnormality of which is not a dangerous one in most cases. It's called mitral valve prolapse. It's a deformity of one of the valves in the heart and some women with mitral valve prolapse have a rapid pulse.

Also medications can do it. If you drink a lot of coffee, your pulse is gonna be rapid, and smoking can increase it too and other medications that you are taking. So the first thing to do if you think you have a rapid pulse, count it and then give that number to your doctor, see whether it's regular. If it's irregular, you should have an electrical cardiogram(心电图）to see if there are extra beats. But that's the story we'll elaborate on... "

And I remember when I was a candy striper, don't use your thumb, 'cause it has its own pulse.

Why doctors use their fingers?

Yes. Smart!

OK. Alright.
