Pacemaker: Supporting the Heart with Modern Technology
A pacemaker is one of the most remarkable achievements in modern medical technology, offering hope and stability to individuals living with irregular heart rhythms. For people whose hearts beat too slowly, skip beats, or fail to maintain a steady rhythm, a pacemaker acts like a silent guardian—constantly monitoring electrical signals and stepping in when needed. Over the years, these tiny devices have evolved from large external instruments to compact, long-lasting implants that significantly improve quality of life.
At its core, a pacemaker works by sending small electrical impulses to the heart muscles whenever it detects an abnormal rhythm. This helps restore a natural heartbeat and ensures consistent blood flow throughout the body. The device consists of two main components: a pulse generator and one or more leads. The pulse generator houses the battery and circuitry that produce electrical signals, while the leads carry…
