All right.

In this question, we are addressing the cardiac pacemaker, which if it's cardiac, we are addressing the heart, the pace of the heart.
00:20
Okay, so essentially the pacemaker is what sets the pace of the heartbeat.
00:42
In other words, your heartbeat rate.
00:45
Now your heart runs on a basis of electrical signals.
01:00
Those electrical signals are what we record in ekgs.
01:06
That's why it can be picked up because there's a series of electrical signals.
01:10
So how does it start? it starts at a point in the heart called the s -a -node.
01:29
All right.
01:30
It stands for sino -h -r -e -r -e.
01:32
Node and it's a little section that's found in the atrial area.
01:38
That's why it's called the sinus, which is a cavity atrial node.
01:43
It's right there...
