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.
the sinoatrial node is the hearts natural pacemaker.
SA node (sinoauricular node)
Sa node
it adjusts the heart rate to correspond to the body's need for oxygen

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.
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 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.
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.
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.
