Implantable loop recorder (Reveal LINQ)

Patient information A-Z

This leaflet is for patients who have had an implantable loop recorder implanted. The type used at Addenbrooke’s is called a 'Reveal LINQ'. This leaflet explains how to use the equipment provided to you along with your implant.

Your Reveal LINQ

Your implanted Reveal LINQ is a heart rhythm monitoring device that is programmed to detect abnormally fast or slow heart rhythms. If these abnormal rhythms are detected, a recording will be made on the device and will be automatically sent to Addenbrooke’s Hospital via your home monitor.

Your home monitor

Place your home monitor within two metres of your bed. It will communicate with your implanted Reveal LINQ every night and send an automatic download to Addenbrooke’s if any fast or slow heart rhythms have been recorded. It is possible your monitor may become disconnected. If this happens you will receive a letter in the post asking you to perform a manual download, and telling you how to do this.

Setting up your monitor

Three blue boxes in a row with arrows between them pointing to the right. From left to right, white text in the boxes reads 'plug in to mains', 'press grey button to wake it up', 'follow on screen instructions'

Your patient assist device

Patient assist device, labelled: success light (green), searching light (blue), record symptom button, connection slot.

Use your patient assist device when you experience the symptoms for which you have had the Reveal LINQ implanted. To do this, follow the instructions on the ‘quick reference card’.

  1. Record symptom button: press this button to record ECG when symptomatic
  2. Searching light: this flashes blue to indicate that you should hold the device over the Reveal LINQ ICM
  3. Success light: this illuminates green when the symptom has been successfully marked
  4. Connection slot: enables attachment to an item such as a key chain or lanyard

The patient assist acts much like a remote control. After pressing the button, a recording of your heart rhythm will be stored in the implanted device.

Try to activate the patient assist within five minutes of symptom onset (unusual heart beat etc) as the recording of your heart rhythm will be captured from about five minutes before activation of the device.

Non-urgent advice: Do

✔Call Ward K2 at Addenbrooke’s once you have made four symptom recordings, or if you have a particularly severe symptom episode.

✔Use the activator even if your symptoms have finished.

✔Keep the patient assist and your ID card with you at all times.

Urgent advice: Don't

❌Do not use the patient assist when you are not experiencing symptoms – it takes a physiologist a minimum of 20 minutes to review, analyse and report each transmission – please use your activator responsibly.

❌Do not touch the home monitor unless instructed to do so by Addenbrooke’s Hospital.

Whenever you use your patient assist to record a symptomatic episode, you must also call ward K2 at Addenbrooke’s Hospital on 01223 256233 From Monday to Friday between 09:00 (9am) and 17:00 (5pm); a member of staff will ask you some questions about the symptoms you experienced. You can also email Addenbrooke's spacing.

Four separate recordings can be stored on the implanted device at any one time. Subsequent recordings will overwrite the first recording that has been made. During the night, any symptomatic episodes that have been recorded by you will be sent to Addenbrooke’s Hospital.

Please be aware that staff are available to review your transmitted information during the normal working hours listed above. If you are experiencing symptoms which need immediate medical attention, please contact your GP or out-of-hours service.
