A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
The contraction of heart (cardiac) muscle in all animals with hearts is initiated by chemical impulses. The rate at which these impulses fire controls the heart rate. The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.
The sinoatrial node is considered the pacemaker of the heart.
A "pacemaker" is a small device that is placed under the skin of your chest or abdomen to help control abnormal heart rhythms, usually used for people with irregular heart beats.
The SA node, the natural pacemaker of the heart, is found in the right atrium of the heart.

A pacemaker is a device inserted into the heart to regulate the heart beats or heart rate
The control unit for the pacemaker was developed by Dr. Paul Zoll in the 1950s, who created the first external pacemaker. However, the first fully implantable pacemaker was designed by Dr. Rune Elmqvist and Dr. Åke Senning in 1958. Their collaboration led to the creation of a device that could regulate heart rhythm without external power sources.
The pacemaker is located on the outside of the right atrium.
The heart's "pacemaker" is the SA (sinoatrial) node.
A pacemaker delivers an electric stimulus to the heart.
