The implantable loop recorder is recommended for a patient who has fainting spells that happen less than once per month. Many times a tilt table test or an electrophysiology study are performed prior to implantation, if no cause for the fainting can be found, a loop recorder may be recommended.
The device is inserted underneath the skin of the chest close to the heart. It is about the size of a thumb drive. The device records arrhythmias automatically and on-demand for up to eighteen months. Usually it is removed if a diagnosis is made or if the battery runs out. The device records events until it is removed or the battery runs out. These events can be reviewed in your provider’s office.
