PATHOLOGY

Detailed explanation-1: -A pacemaker is a small device that’s placed (implanted) in the chest to help control the heartbeat. It’s used to prevent the heart from beating too slowly. Implanting a pacemaker in the chest requires a surgical procedure. A pacemaker is also called a cardiac pacing device.

Detailed explanation-2: -Artificial pacemakers are electronic devices that stimulate the heart with electrical impulses to maintain or restore a normal rhythm in people with slow heart rhythms.

Detailed explanation-3: -Pacemakers send electrical pulses to help your heart beat at a normal rate and rhythm. Pacemakers can also be used to help your heart chambers beat in sync so your heart can pump blood more efficiently to your body. This may be needed if you have heart failure.
