Cardiac Loop Recorder Insertion
WHAT YOU NEED TO KNOW:
What do I need to know about cardiac loop recorder insertion (LRI)?
- A cardiac loop recorder is a device that continuously records your heart rhythm. It is also called an insertable cardiac monitor or implantable loop recorder. It is a small device, about the size of a USB memory stick. It is implanted in your left chest area, just under the skin. The device records patterns of your heart's rhythm, called an EKG.
- Loop recorders are used to help diagnose heart rhythm problems that do not have a clear cause. They are also used when symptoms do not happen often, and other heart monitors have not worked. A loop recorder may be recommended for people with a fast or irregular heartbeat, fainting, seizures, or dizziness. It can also be used for long-term monitoring in people with atrial fibrillation or in people who have had a heart attack.
- You may receive a handheld controller. You press a button on the controller when you have symptoms, such as dizziness or lightheadedness. The device will record an EKG at that moment. The recording can help your healthcare provider see if your symptoms may be caused by heart rhythm problems.
- The device will be removed after it has collected enough data. It can be in place for up to 3 years. The procedure to remove the device is similar to the procedure used to implant it.
How do I prepare for cardiac LRI?
Your healthcare provider will talk to you about how to prepare for the procedure. He or she may tell you not to eat or drink anything for at least 6 hours before your procedure. He or she will tell you what medicines to take or not take on the day of your surgery. If you take blood thinners, you may need to stop taking them several days or weeks before the procedure. You may be given antibiotics just before the procedure to help prevent an infection. Arrange for someone to drive you home and stay with you for at least 24 hours.
What will happen during cardiac LRI?
Local anesthesia will be used to numb your skin. You will be given a mild sedative to help you relax, but you will be awake during the procedure. Children may receive general anesthesia so they sleep through the procedure. A small incision will be made on the left side of your chest, or under your arm. The loop recorder device will be implanted just under the skin. You will see a small lump where the recorder is placed. Your incision will be closed with stitches and covered with a bandage.
What will happen after cardiac LRI?
You will be taken to a recovery area to rest. You may have discomfort or bruising at the implant site for up to 2 weeks. When your healthcare provider sees that you are okay, you will be allowed to go home.
What are the risks of cardiac LRI?
You may bleed more than expected or develop an infection at the implant site. The procedure may cause damage to your heart or blood vessels. The device may stop working.
