Pacemakers: A Lifeline for Heart Health
A pacemaker is a small, sophisticated medical device that plays a critical role in regulating the heart's rhythm. For people with arrhythmias, heart block, or other cardiac conditions, the heart may beat too slowly, too fast, or irregularly. Pacemakers step in to ensure the heart maintains a stable, consistent rhythm, improving both health and quality of life.
The device is usually implanted under the skin near the collarbone, with thin wires called leads running into the heart. These leads monitor the heart’s electrical activity and deliver precise electrical impulses when necessary. The technology is designed to respond only when needed, allowing the heart to function naturally when its rhythm is normal. This targeted intervention minimizes unnecessary stimulation and reduces stress on the heart.
Modern pacemakers are highly advanced. Some are single-chamber devices, pacing either the right atrium or right ventricle. Others are dual-chamber pacemakers,…
