The correct answer would be a. pacemaker.

A pacemaker is a medical device implanted in a chest or abdomen of a person suffering from arrhythmias (irregular heart rate; too fast, too slow, or irregular rhythm).

It is used in monitoring and maintaining a heart rate of a person.

It consists of a computerized generator, battery, and wires with sensors.

If an abnormal rhythm is detected by a device, it generates electrical impulses which help in contraction of heart muscles and thus, help in regulating the electrical conduction system of a heart.
