A pacemaker is a small, implantable device designed to regulate and stabilize the heart's rhythm. It functions by emitting electrical pulses that prompt the heart to beat at a steady and controlled rate. This technology is particularly vital for individuals with irregular heartbeats or conditions that affect the heart's natural pacemaking system. The pacemaker continuously monitors the heart's activity and intervenes when necessary, ensuring that it beats in a coordinated and efficient manner. As a result, patients with pacemakers often experience improved quality of life and reduced symptoms associated with heart rhythm abnormalities. Over the years, advancements in pacemaker technology have led to more sophisticated and customizable devices, allowing healthcare professionals to tailor treatment plans to individual patient needs.
