A pacemaker only works when it senses trouble with the heartbeat. For example, if the heart beats too slowly, the pacemaker sends electrical signals to correct the beat.
A pacemaker is a small device that helps regulate heart rate and rhythm by sending electrical impulses to the heart muscle. Learn how it works.
What’s it like having a pacemaker? Getting a pacemaker might sound intimidating, but the process is simpler and more routine than you might expect.
A pacemaker is a small, battery-operated device that helps the heart beat in a regular rhythm. Traditional pacemakers have three parts: a generator, wires (leads) and sensors (electrodes).
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart.
Learn what pacemakers are and how they work, as well as the signs that your pacemaker needs to be replaced.
A pacemaker is designed to prevent the heart from beating too slowly. For example, the heart may not be able to generate each electrical impulse, it may temporarily stop, or the nerve that carries the electricity from the top of the heart to the bottom chambers may wear out.
Who Should Get a Pacemaker and What to Know About Living With One
What is a pacemaker? A pacemaker is composed of three parts: a pulse generator, one or more leads, and an electrode on each lead. A pacemaker signals the heart to beat when the heartbeat is too slow or irregular.
A pacemaker is a small, battery-operated device. This device senses when your heart is beating too slowly. It sends a signal to your heart that makes your heart beat at the correct pace.
