Pacemaker

WHAT YOU NEED TO KNOW:

What is a pacemaker?

A pacemaker is a small device placed in your chest. It helps control your heartbeat. You may need a pacemaker if your heartbeat is too slow, too fast, or irregular. A pacemaker is about the size of a large wristwatch. It is made up of flexible wires (leads) with sensors, a battery, pulse generator, and a small computer. The sensors measure your heartbeat. They send this information to the computer. The computer causes the generator to send electrical impulses to your heart. This makes your heart beat correctly. Some pacemakers can also record your heart rate and rhythm.


How do I prepare for a pacemaker insertion?

Your healthcare provider will talk to you about how to prepare for the procedure. You may need a blood test, chest x-ray, or other tests before your procedure. These tests will help your provider plan your procedure. Your healthcare provider may tell you not to eat or drink anything after midnight on the day of your procedure. He or she will tell you what medicines to take or not take on the day of your procedure. You may be given an antibiotic to prevent infection. Tell a healthcare provider if you have ever had an allergic reaction to an antibiotic.

What will happen during a pacemaker insertion?

  • You may be given IV sedation to make you feel calm and relaxed during the procedure. You may also be given local anesthesia to numb the procedure area. With local anesthesia, you may still feel pressure or pushing, but you should not feel any pain.
  • Your healthcare provider will insert a needle into a large vein in your chest or neck. Next, he or she will guide the wires through the needle and into your heart. Your healthcare provider will make an incision in your chest and insert the pacemaker. He or she will connect the wires in your heart to the pacemaker. He or she will also make sure the pacemaker is working correctly. Your incisions will be closed with stitches, medical glue, or Steri-strips™. They will be covered with a bandage.

What will happen after a pacemaker insertion?

Healthcare providers will monitor your heartbeat. You may need a chest x-ray and an EKG. These tests will make sure your pacemaker is in the correct position and working correctly. You may have bruising or pain near your incision. This should get better in a few days. You may need to spend a night in the hospital.

What are the risks of a pacemaker insertion?

You may bleed more than expected or get an infection. The pacemaker could move out of place and cause pain and bleeding. The leads may cause a hole in your lung, heart, or blood vessel. Your pacemaker may stop working correctly. This can cause an irregular heartbeat, heart failure, blood clots, or other problems. These problems may become life-threatening.
