How is an implantable loop recorder procedure performed?

An implantable loop recorder is inserted by an electrophysiologist, a physician who specializes in the heart’s electrical system. The procedure is performed in the hospital under local anesthesia. The device, which is about the size of a flattened AA battery, is implanted through an incision in the chest, which is closed with stitches after implantation of the device. You can typically return home and to normal activity the same day.

Your physician will be able to view data that you have transmitted or by using a specialized computer in the office called an interrogator. After a diagnosis has been made, or at the end of the device’s battery life, the recorder may be removed in a procedure very similar to the one used for insertion.
