Pacemakers are small medical devices implanted in the chest to help regulate the heartbeat. They are used primarily for patients with arrhythmias, conditions where the heart beats too slowly, too quickly, or irregularly. By sending electrical impulses to the heart, pacemakers ensure it maintains a proper rhythm, improving blood flow and overall heart function. The device consists of a pulse generator and leads that connect to the heart. Modern pacemakers are often equipped with advanced features, such as remote monitoring capabilities, allowing healthcare providers to track a patient's heart health without requiring frequent office visits. This innovation enhances patient care and safety.
