It is a device that can be used short term externally to correct an irregular heartbeat or it can be inserted internally to control the heartbeat. It runs on batteries that have to be changed periodically through a surgical procedure.
Your heart has a normal pacemaker that keeps a rhythm so the four chambers beat in the right order. Some people's don't work properly and an artificial one is implanted to do the job. The sound your heart makes is the normal rhythm.
pace maker of heart is SAN(sino auricular node) while pace setter is AVN(auriculo ventricular node).
The sinoatrial node is also known as the pacemaker.

The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
A pacemaker may increase the regularity and reliability of the heart beat. If coronary arteries are clogged, a pacemaker alone may not restore normal cardiac function.
The rate and pace of the heart are set by the SA node. There are backup systems in place if the SA node fails to do its job.
Pace Maker
The pace maker uses electrical impulses to regulate heart rate. It is used when the bodies own impulses from the brain are not able to do the job anymore.
The natural pacemaker of the heart is called the sinus node. This is made up of a cluster of cells that are in the upper right part of the wall of the right atrium.

the Sino Atrial Node (SA Node) is the pace maker of the heart that receives singles from the brain.
It is an electronic device known as a pace-maker.
Specialized heart muscle cells in the sino-atrial (SA) node which is located in the right atrium. These serve as the heart's "pace maker".
Sympathetic nerve stimulate the pace maker. So that heart rate increases. Parasympathetic stimulation decreases the heart rate.
I believe it is called the Pace maker (not sure if it's one word or two). From what I it emits an electric pulse down the center of the heart, or septum, and causes the heart to contract. I do not believe it has a direct connection to the brain, but it may. I'm not entirely sure about any of this.
nothing that's why they made a pace maker well they did have a machine you were hooked up to and if your heart stoped it shocked you i don't know what its though
John Hopps, a Canadian, invented the first heart pacemaker. At the age of 21, He was able to build the first pacemaker in 1950.
