One way to measure it would be to put electrodes directly into the heart

检测的一个方法就是将电极直接插入心脏
and physically put them right near the site of action

安置于活动发生部位的周围
and measure exactly what's happening.

确切的检测究竟发生了什么
That could be--you could get a very detailed picture

那有可能-- 那样的话你可以得到一个
of what's happening in the heart that way.

关于心脏电生理功能的非常精细的图片
That can be done but that's an invasive process.

那可以实现但是那是有创的
There are cardiologists that do that,

心脏科医师是这样做的
they do this everyday on people.

每天如此
They put a catheter into your heart,

他们将一个导管置入心脏
a catheter that goes through one of the vessels,

一个导管经过血管
an artery in your leg.

经过大腿上的一条动脉
It's pushed up into the heart

导管一直向上伸至心脏
