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.

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.
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.
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.
A woman who has lupus and is pregnant may have a child with neonatal lupus or may have a totally healthy child. Babies with neonatal lupus may have the disease resolve in a few months or they may have congenital heart block, requiring the installation of a pace maker to regulate the heart beat.
this is true since the arteries keep the same pace with the heart.
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.
