A pacemaker is a small, battery-powered device that helps manage irregular heartbeats, known as arrhythmias
. Here are some key points about pacemakers:
What is a Pacemaker? A pacemaker is implanted under the skin, usually near the collarbone, and it sends electrical impulses to the heart to maintain a regular heartbeat .
Types of Pacemakers Single-Chamber Pacemaker: Sends electrical signals to either the right atrium or right ventricle1 .
Dual-Chamber Pacemaker: Sends signals to both the right atrium and right ventricle1 .
Biventricular Pacemaker: Sends signals to the right atrium, right ventricle, and left ventricle, helping the heart chambers beat in sync1 .
Wireless Pacemaker: A newer type that combines the pulse generator and electrodes into a single device about the size of a pill1 .
How Does it Work? The pacemaker monitors the heart's electrical activity and sends electrical signals to the heart muscle if it detects an irregular heartbeat3 . This helps regulate the timing and sequence of the heartbeat3 .
Who Needs a Pacemaker? People with arrhythmias, such as bradycardia (slow heart rate) or tachycardia (fast heart rate), may need a pacemaker1 . It can also be used to treat some types of heart failure1 .
Procedure The implantation of a pacemaker involves a minor surgical procedure where the device is placed under the skin and connected to the heart via leads1 .
Risks and Precautions While pacemakers are generally safe, there are some risks associated with the procedure, such as infection or lead displacement1 . It's important to follow your doctor's advice on precautions and care.
