The problem
Short monitors can’t catch a rare arrhythmia.
If your blackouts, palpitations or suspected AF happen only every few weeks, a Holter or patch will almost always come back blank. An ILR waits — quietly, continuously — for up to three years.
-
Blackouts with no rhythm captured yet?
The ILR runs continuously until the next event, so the diagnostic rhythm is recorded when it happens.
-
Cryptogenic stroke and looking for AF?
NICE-aligned pathway — implant, monitor, treat any occult AF that emerges over months.
-
Ablation done, but was it durable?
Continuous surveillance beats spot checks — you know if AF or SVT has returned.
The journey
From enquiry to a device transmitting — what happens, in order.
One electrophysiologist from first message to implanted device — 30 minutes in the room, then the device does the waiting.

After
Daily transmissions and review
Your rhythm streams to your electrophysiologist every night. You’re contacted only if a clinically important episode is captured.
Typical end-to-end: same week. Urgent post-stroke pathway: within 48 hours.
What it shows
When an ILR is the right monitor.
The eight clinical questions an ILR is designed to answer — when shorter monitors have run out of runway.
-
Unexplained syncope
Continuous recording finally captures the rhythm during a blackout — the diagnostic yield a Holter rarely reaches.
-
Palpitations without a documented arrhythmia
When shorter monitors have drawn a blank but the symptoms keep coming, the ILR waits as long as it takes.
-
Suspected atrial fibrillation
For paroxysmal AF that shorter monitors miss — a critical call before starting anticoagulation.
-
Cryptogenic stroke pathway
NICE recommends prolonged rhythm monitoring after a stroke of unclear cause to detect occult AF.
-
Post-ablation surveillance
Confirms whether an AF or SVT ablation has held, with continuous rhythm data over months, not days.
-
When Holter monitors don’t catch it
Symptoms every few weeks are invisible to a 24- or 48-hour monitor. An ILR watches for up to three years.
-
Familial arrhythmia surveillance
Long-term monitoring in inherited channelopathies or cardiomyopathies where sudden events are possible.
-
Red flag: recurrent collapse with injury
If you’ve fallen and hurt yourself during a blackout, the pathway is accelerated — don’t wait weeks.
Pathway types
Every step in the ILR pathway.
From the first insertion to removal — what each part of the pathway is for.
-
ILR insertion
The core procedure — a small under-skin recorder placed left of the breastbone in about 30 minutes under local anaesthetic.
-
ILR + cardiology consult
Combines the insertion with a same-visit consultation to plan the pathway and interpret prior tests.
-
Remote monitoring
A bedside transmitter uploads your rhythm to your electrophysiologist every night — included with every implant.
-
ILR removal
A short procedure at end of battery life, or once a diagnosis and therapy plan are secure.
-
Post-stroke ILR pathway
A NICE-aligned pathway for cryptogenic stroke — implant, monitor, treat any occult AF.
-
Post-ablation surveillance
Rhythm monitoring for months after an AF or SVT ablation to confirm durable success.
-
Paediatric ILR (specialist)
Under-16 implants arranged with a paediatric electrophysiologist at a specialist centre.
-
Repeat implant
A second device at end of battery life when the clinical question is still open.

24-hour transmission alert pathway
Safety and eligibility
A small procedure — but a device that lives with you for years.
The insertion is quick and low-risk. The practical points are wound care in the first week and knowing how to live with the device afterwards.
-
A very small local anaesthetic procedure
Done in a clean procedure room, not a full operating theatre. You’re awake and comfortable throughout.
-
Single incision, single stitch
A small cut about 1cm long left of the breastbone, closed with one dissolvable stitch and skin glue.
-
Minor bruising and tenderness
Expect a bruise and mild soreness for a few days. Simple painkillers are usually enough.
-
MRI-conditional (declare before any scan)
Modern ILRs are MRI-safe under specific conditions. Always show your device card to the MRI team before scanning.
-
Small infection risk
Under 1%. Keep the site dry for 48 hours and follow the wound-care sheet. Contact us if it becomes hot, red or leaks.
-
Battery life up to ~3 years
The device records continuously for up to three years, then is removed or replaced depending on the answer.
-
You push a button when you have symptoms
A small handset lets you tag the exact moment of a palpitation, dizzy spell or blackout for the electrophysiologist to review.
-
Remote transmissions daily
The bedside monitor uploads your rhythm each night. Keep it plugged in within a few metres of where you sleep.
-
Always share your device card at airports
Show the card at security — walk-through metal detectors and body scanners are fine. Avoid lingering near the handheld wand.
Reading your report
Months of data, a single actionable page.
Whether the ILR runs for 3 months or 3 years, the summary keeps to the same four parts.
A quiet reminder
Push the symptom button. It’s the single most useful thing you can do.
Correlating a rhythm with the exact moment you felt symptoms is what turns raw data into a diagnosis.

Frequently asked
Everything we get asked about implantable loop recorders.
Quick answers on cost, pain, driving, MRI, battery life and what happens after a diagnosis.
-
What does an implantable loop recorder actually do?
An ILR is a small under-skin recorder — about the size of three matchsticks — that continuously watches your heart rhythm for up to three years. It stores any abnormal beats automatically and lets you tag the exact moment you feel symptoms. Your rhythm is uploaded remotely each night to your electrophysiologist.
-
How is it different from a Holter or patch monitor?
A Holter records for 24–48 hours; a patch monitor for up to 14 days. An ILR records continuously for up to three years, so it catches symptoms that happen only every few weeks or months. If your shorter monitor was blank but your symptoms keep coming, an ILR is often the logical next step.
-
Does the insertion hurt?
You’ll feel a sting from the local anaesthetic, then pressure but no pain during the 30-minute procedure. Afterwards, expect tenderness and a bruise for a few days — most people manage with paracetamol.
-
How much does an ILR cost privately in London?
ILR insertion typically costs £3,500–£7,000, depending on the device (Reveal LINQ, Confirm Rx) and clinic. Remote monitoring is included. A same-visit cardiology consultation adds around £300–£500. We confirm a firm figure within one working day.
-
Can I drive after the procedure?
Yes, usually the same day, provided you’ve not had a recent blackout that would restrict you under DVLA rules. If you’re here because of syncope, driving may be paused until a diagnosis is made — your electrophysiologist will advise.
-
Is it safe to have an MRI with an ILR?
Yes — modern ILRs are MRI-conditional, meaning they can be scanned under specific conditions. Always show your device card to the MRI team before any scan, and they will arrange the appropriate protocol.
-
How long does the battery last?
Up to about three years of continuous recording. Once a diagnosis and treatment plan are secure, the device can be removed in a short outpatient procedure. If the clinical question is still open at end of life, a second device can be implanted.
-
How do I send a recording when I have symptoms?
You’re given a small handset. When you feel a palpitation, dizzy spell or blackout, press the button — this tags the exact moment for your electrophysiologist to review. Otherwise, transmissions happen automatically each night via the bedside monitor.
-
What if the ILR shows I need a pacemaker or ICD?
The ILR is diagnostic, not therapeutic — it tells us whether you need treatment. If it captures a significant pause, complete heart block, sustained VT or another rhythm that needs a device, your electrophysiologist arranges the pacemaker or ICD as a separate procedure.
-
When should I see a GP urgently instead?
If you have chest pain, severe breathlessness, or a blackout with injury while waiting for the procedure, seek urgent assessment. Call 999 for chest pain that is severe or new, or for a collapse that hasn’t fully resolved.
