Pacemaker | Dr.Ishwar Zanwar

A pacemaker is a small device that is surgically implanted under the skin of the chest. It's designed to help regulate the heartbeat for people who have an abnormal heart rhythm, known as arrhythmia.

The pacemaker has two main components: a pulse generator, which contains a battery and the circuitry that controls the device, and one or more leads, which are thin wires that are inserted into the heart through a vein and connect the pulse generator to the heart.

 

 

The pacemaker works by sending small electrical impulses to the heart through the leads, which help to regulate the heart's rhythm. Pacemakers have the ability to sense the heart's own electrical activity and will only send an impulse if it detects that the heart's rhythm is too slow.

Pacemakers are used to treat various types of arrhythmias, such as bradycardia, which is a slow heartbeat, and heart block, which is a delay or interruption in the electrical signals that control the heartbeat. Pacemakers are also used in patients who have had a heart attack and have damage to the conduction system of the heart.

The procedure is usually done under general anesthesia and the recovery time is usually short, patients may experience some pain and swelling at the incision site. Pacemakers are designed to last for several years and will need regular follow-ups to ensure it is working properly and to update the programming if needed.
