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
and then there are recording electrodes on the end

在其末端有记录的电极
and they can measure electrical activity directly

电极可以直接检测
in the heart at different locations.

心脏不同部位的心电活动
That's called cardiac catheterization and cardiac electrophysiology,

这就是心导管置入术以及心脏电生理学
