Cardiac Pacemaker – Restoring Rhythm and Supporting a Steady Heartbeat
A cardiac pacemaker is one of the most remarkable examples of medical technology improving human life by restoring order to the heart’s rhythm. For individuals living with arrhythmias—conditions where the heart beats too slowly, too fast, or irregularly—a pacemaker offers stability, safety, and the opportunity to return to everyday activities with greater confidence. Its evolution over decades has transformed cardiac care, turning once life-threatening rhythm disorders into manageable conditions.
At its core, a pacemaker is a small, battery-powered device implanted under the skin, typically near the collarbone. It consists of a pulse generator and one or more leads that extend into the heart. These leads monitor the heart’s electrical activity and deliver gentle impulses when needed to correct abnormal rhythms. The goal is simple yet powerful: ensure that the heart maintains a healthy, consistent beat.
Pacemakers are most often used to treat bradycardia, a condition where the heart beats too…
