A pacemaker is a small medical device implanted in the chest to help regulate irregular heartbeats, known as arrhythmias. It consists of a pulse generator and leads that deliver electrical impulses to the heart, ensuring it beats at a normal rate. Pacemakers are commonly used in patients with bradycardia, where the heart beats too slowly, or other rhythm disorders. The procedure for implantation is minimally invasive, often performed under local anesthesia. Modern pacemakers can adjust their pacing based on the patient’s activity levels and can even be monitored remotely. This technology has significantly improved the quality of life for many patients, reducing symptoms like fatigue and dizziness.

Ongoing advancements continue to enhance pacemaker design and functionality, making them a vital tool in cardiac care. Ultimately, pacemakers play a crucial role in maintaining heart health and overall well-being.
