What purpose does an artificial pacemaker serve?

Answer 1

A pacemaker is a medical device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's native pacemaker is not fast enough, or there is a block in the heart's electrical conduction system.
It takes over the function of the sino-atrial node, that is the natural pacemaker of the heart. A pacemaker gives impulses so that the heart contracts and the blood flows out

Answer 2

It compensates for a failure of the heart's own pacemaker nerve circuit that would normally keep it beating in the correct rhythm.

It contains an electronic circuit and is connected by wires to the heart muscle. The electronic circuit generates pulses of current in the correct rhythm to keep the heart beating.

Answer 3

An Artificial Pacemaker basically regulates the rate of the heart beat depending on the needs of the body.

Answer 4

It takes the place of your SA node and so sends out electric pulses that depolarize your heart and allow it to pump.

Answer 5

The Artificial Pacemakers alters your heart rate therefore helping your body meet its need.

Answer 6

An artificial pacemaker works by detecting changes in the heart's rhythm. If it detects a 'problem' - it delivers a shock to the heart's muscle - returning the heartbeat to a regular beat.
