Your heart produces electrical impulses that help your muscles contract and release blood. When your heart cannot regulate this function, a pacemaker device generates an electrical charge that you will not feel, making the heart contract and pump vital blood throughout the body.
A pacemaker is a small battery-powered device implanted under the skin next to the heart that detects your heart rate and uses an electrical signal similar to your heart’s natural signal to adjust it to beat normally.
Doctors can use pacemakers to monitor heart conditions, and devices can record many important health indicators, including heart activity. For example, a pacemaker is used to treat arrhythmias such as atrial fibrillation. It can store data about the wearer’s heart and automatically adjust its electrical pulse to the heart based on the information it records.
