The implantable loop recorder is for patients who have recurrent fainting spells that happen less than once per month. Usually a tilt table test and an electrophysiology study are performed prior to implantation. These tests usually must be normal prior to implanting this device.
The device is inserted underneath your skin of your chest close to your heart. It is about the size of a lighter. The device records arrhythmias automatically and on-demand for up to eighteen months. Usually it is explanted if a diagnosis is made or if the battery runs out.The device can record an infinite number of events. These events can be reviewed in your doctor’s office.

- An IV (intravenous line) inserted in your arm administers sedatives, medications, and fluids during the procedure.
- Your doctor will explain the procedure and its potential benefits and risks to you.
During the procedure
- A local anesthetic is injected to numb the area where the loop recorder will be implanted.
- Your doctor will make an incision alongside the sternum to create a “pocket” under the skin.
- After the device is in the correct position, it is tested to make sure it senses your heart’s electrical signals.
After the procedure
