Loop Recorder

An implantable loop recorder (ILR) is a small device placed just under the skin of the chest to continuously monitor and record your heart’s electrical activity over an extended period.

How the loop recorder works

The ILR continuously tracks your heart rhythm and automatically records any abnormal activity it detects.

You may be given a smartphone app or other device to manually prompt the device to record if you feel symptoms such as dizziness or palpitations. The recorded data is sent to your medical team, either during clinic visits or remotely, to help diagnose potential heart rhythm disorders.

Why you might need a loop recorder

  • Unexplained fainting spells.
  • Unexplained strokes, to check for hidden arrhythmias.
  • Symptoms that standard ECGs or Holter monitors haven’t explained.

What to expect

The procedure is minimally invasive and typically done under local anaesthetic in a hospital. A small incision is made in your upper chest, and the device is gently inserted under the skin. The incision is closed with stitches, and most patients go home the same day.

You may notice some mild discomfort or swelling at the implant site, which usually resolves quickly.
