An implantable loop recorder is a small device that is implanted under the skin to help identify the causes of fainting. Syncope (or fainting) is a temporary loss of consciousness. Certain heart disorders can cause fainting, such as abnormal heartbeats called arrhythmias.
The implantable loop recorder is surgically placed under the skin under local anesthesia. The device continuously records heart activity similar to an ECG for up to 2 years. If the patient experiences an episode of fainting the device is activated to save the recording before, during, and after the episode. The recordings can then be evaluated by a physician to help determine the cause of fainting. Once the period of recording is completed, the device is surgically removed under local anesthesia.
