Permanent Pacemaker Implantation

When would I need a permanent pacemaker implantation?

Pacemakers are medical devices for treating a slow heartbeat (bradycardia). The small device monitors your heart rate and sends an electrical signal to stimulate a contraction when your heart beats too slowly. Bradycardia is defined as a heart rate lower than 60 beats per minute. However, young and athletic people may have a naturally low rate. If you have any concerns, the Florida Heart, Vein and Vascular Institute team can determine a healthy heartbeat for you. Bradycardia has many possible causes. Here are a few examples:

• Damaged heart tissue caused by heart disease, a heart attack, or aging
• Problems with the heart’s electrical system
• Hereditary heart defects (a heart condition present at birth)
• Heart inflammation
• Underactive thyroid gland
• Sleep apnea
• Certain medications

Bradycardia may cause chest pain, dizziness, tiring during physical activity, fatigue, and shortness of breath.

What type of pacemaker is best?

You may receive one of two types of pacemakers: a leadless (wireless) pacemaker or a conventional pacemaker. Conventional pacemakers are implanted in your upper chest, with a lead wire running from the device through your blood vessels and into your heart. A leadless Micra doesn’t rely on wires. Instead, it’s a self-contained device and so small it goes directly into your heart. (The Micra is 93% smaller than conventional pacemakers and about the size of a large vitamin capsule). As a result, you don’t have a scar or bump on your chest. While Florida Heart, Vein and Vascular Institute finds the Micra to be among the best pacemakers, if your condition or needs require a different type, your provider will review the other options with you.

What should I expect during a permanent pacemaker implantation?

The Florida Heart, Vein and Vascular Institute team implants the Micra using Medtronic’s specially designed catheter. Your provider makes a tiny incision in your groin and uses it to insert the catheter into a vein. Using real-time imaging, they guide the long, slim, and flexible catheter through your blood vessels and into your heart. Once the catheter enters the targeted heart chamber and reaches the inner wall, your provider releases the device and secures it in the muscle. They use an external programmer to be sure the Micra is working and then remove the catheter. Most people go home the same day, but you’ll need to rest for a day and avoid strenuous activity for a week. Your provider gives you all the information you need to ensure a safe recovery.
