A pacemaker is a small, electronic device implanted under the skin to help regulate the heart’s rhythm. It’s often used for people with certain heart conditions that cause a slow or irregular heartbeat.
When is a Pacemaker Needed?
Pacemakers are typically recommended for people with:
- Bradycardia: A slow heart rate.
- Heart block: A disruption in the electrical signals that control the heart’s rhythm.
- Certain types of arrhythmias: Irregular heart rhythms.
- Heart failure: In some cases, a pacemaker can help improve heart function.
The Pacemaker Procedure
The procedure to implant a pacemaker is typically performed under local anesthesia. A small incision is made in the chest or under the collarbone. The pacemaker device is then inserted and connected to the heart muscle using wires.
Types of Pacemakers
- Single-chamber pacemakers: These pacemakers only stimulate one chamber of the heart (usually the right ventricle).
- Dual-chamber pacemakers: These pacemakers stimulate both the upper and lower chambers of the heart.
- Biventricular pacemakers: These pacemakers stimulate all four chambers of the heart, which can be beneficial for people with heart failure.
Living with a Pacemaker
Once a pacemaker is implanted, it requires regular monitoring by a cardiologist. The battery in the pacemaker typically lasts for several years and may need to be replaced. Most people with pacemakers can live normal, active lives.
Benefits of a Pacemaker
- Improved heart function: A pacemaker can help regulate the heart’s rhythm and improve blood flow.
- Reduced symptoms: Pacemakers can help alleviate symptoms such as fatigue, dizziness, and fainting.
- Improved quality of life: For people with certain heart conditions, a pacemaker can significantly improve their quality of life.
If you have been diagnosed with a heart condition that may require a pacemaker, it’s important to discuss the benefits and risks with your doctor. They can help you determine if a pacemaker is the right treatment for you.
