What you can expect

Before

There's no special preparation for an implantable loop recorder.

During

An implantable loop recorder is placed under the skin on the chest.

The procedure to insert the heart monitor is usually done in a doctor's office or medical center. You'll be awake for the procedure but may be given medicine to relax you (sedative). The area of skin on the chest is numbed. Your doctor makes a tiny incision, inserts the device and closes the incision. The device will stay in place for up to three years.

After

Complications of the procedure are quite uncommon. However, because minor surgery is done to implant the device, you'll need to watch for signs of infection such as redness or swelling. Your doctor and nurse will tell you what to look for. You may need to limit activities until the wound heals.

You'll be given a transmitting device to place beside your bed. The transmitter automatically sends information from your implant to your doctor while you sleep. You can also push a button to send data immediately when you have symptoms.

Your doctor may ask you to keep a diary of your symptoms and when they occur.
