A pacemaker is a small, battery-operated device that is implanted under the skin near the heart to help regulate the heartbeat.
If your heart does not beat at the proper rate, normally 60 to 100 beats per minute, blood is not pumped properly throughout the body.
The pacemaker mimics your heart’s natural pacemaker, sending electrical impulses through the heart muscle to the heart’s chambers. Those electrical signals make the chambers contract normally and pump blood to the body.
A pacemaker is used to treat several heart rhythm conditions, including:
- Hypertrophic myocardia
- Slow heart rhythms
To determine whether a pacemaker is right for you, your physician will run tests to determine the cause and origin of your irregular heart rhythm.
Electrophysiology tests – minimally invasive studies of the electrical activity and pathways of the heart – can include:
- Echocardiogram – produces a moving picture of the heart, using a device called a transducer that is placed on the chest
- Electrocardiogram – measures heart rate, heart rhythm, and strength of electrical signals in the heart
- Holter monitor – records a continuous ECG of the heart's electrical activity using an external device worn by the patient
- Stress tests
