Sep 25, 2024 · Rather, a pacemaker helps regulate the timing and sequence of your heartbeat, as needed. After it is put in, the pacemaker monitors your heart's electrical activity. If your heart rate is too slow, the device will kick in and send a tiny electrical signal to the heart muscle that tells it to squeeze (contract).

A pacemaker is a small battery-operated device that helps the heart beat in a regular rhythm. Traditional pacemakers have three parts: a generator, wires (leads) and sensors (electrodes). Some newer pacemakers are wireless. It produces electrical impulses to help control abnormal heartbeats. It's implanted under the skin through a small incision on...
Your doctor may recommend a pacemaker to make your heart beat more regularly if: 1. Your heartbeat is too slowand often irregular. 2. Your heartbeat is sometimes normal and sometimes too fastor too slow.
