Implantable loop recorder (ILR)

Why is it used?

An implantable loop recorder is a small device, approximately the size of a memory stick. It is usually employed when a doctor has a high suspicion that a patient’s symptoms of black-outs or palpitations are suggestive of an arrhythmia which has not been documented using other investigation.

What does the procedure involve?

This is a device that is placed under the skin, most commonly above the left breast, under local anaesthetic.  The procedure takes approximately 20 minutes. This recording device monitors the heart rhythm continuously for up to 3 years.   More Information
