A pacemaker is a small medical device that helps regulate an abnormal or unusually slow heart rhythm. It may be recommended when the heart’s natural electrical system does not reliably maintain an appropriate heart rate.
Pacemaker implantation is a procedure performed to place the device and its leads in the appropriate location. The device monitors the heart and provides electrical impulses when needed.
The procedure is performed using local anesthesia and, when appropriate, medication to help you relax. A small incision is made, commonly near the upper chest.
One or more leads are guided through a blood vessel into the heart. The pacemaker generator is positioned beneath the skin and connected to the leads. The device is tested before the incision is closed to ensure it is functioning properly.
Pacemakers may be recommended for certain heart rhythm conditions that cause the heart to beat too slowly or irregularly. Symptoms can include fatigue, dizziness, weakness, or fainting depending on the condition.
Not every abnormal rhythm requires a pacemaker. A cardiologist evaluates your heart rhythm and overall health before recommending implantation.
A traditional pacemaker generator is commonly placed beneath the skin in the upper chest. One or more thin leads connect the generator to the heart. The exact configuration depends on the type of pacemaker required. Your cardiology team will explain the device selected for your condition.
Many pacemaker procedures are performed with local anesthesia and medication to help you remain comfortable and relaxed. You may be awake enough to communicate with the medical team.
The specific anesthesia plan varies according to the procedure and your health. Your provider will explain what to expect before implantation.
The lifespan of a pacemaker depends on factors such as the device type and how frequently it needs to deliver therapy. Regular follow-up allows the medical team to monitor battery status and device performance. Eventually, the generator may need to be replaced. Your provider will explain the expected monitoring schedule.
Yes. Regular follow-up is an important part of living with a pacemaker.
Your healthcare team checks the device, leads, battery, and heart rhythm. You will also receive instructions regarding activity and care of the incision after implantation. Always contact your care team if you experience concerning symptoms.
