Concierge cardiac electrophysiology · London
Cardiac device checks, pacemaker, ICD and CRT interrogation — the standard follow-up you need.
A structured interrogation of implanted cardiac devices — pacemaker, implantable defibrillator (ICD), cardiac resynchronisation therapy (CRT) or loop recorder. Checks battery, leads, arrhythmia detections and stored electrograms — usually every 6–12 months, plus remote-monitoring alerts.

Key facts
What a cardiac device check actually does.
The six numbers your electrophysiology team is really looking at.
-
Definition
In-clinic or remote interrogation of an implanted cardiac device.
-
Frequency
Every 6–12 months in clinic, with continuous remote monitoring in between.
-
Battery and leads
Reviews battery voltage, lead integrity, sensing and pacing thresholds.
-
Arrhythmia detection
Quantifies AF burden, ventricular tachycardia (VT) and ventricular fibrillation (VF).
-
Therapy optimisation
Guides medication changes and CRT programming for best clinical response.
-
Early failure detection
Enables early identification of lead failure before clinical events occur.
The problem
A device check is only as good as who reads it.
The numbers are the answer — and the physiologist and electrophysiologist reading them decide how they translate into a programming change, medication tweak or generator swap. We route you to that team, not a generalist.
-
Had an ICD shock?
We arrange an urgent interrogation and route findings to an electrophysiologist the same day.
-
Remote-monitoring alert?
We triage the alert against a clinic slot within days, not weeks.
-
Routine 6–12 monthly check due?
We book the appointment, handle insurer paperwork and set up remote monitoring if you don’t have it.

Within one working day: appointment with a cardiac physiologist under a consultant electrophysiologist. Bring your device ID card.
- 03
Before
We arrange the appointment
Often same or next day, including evenings and Saturdays. Insurer pre-authorisation handled.
- 04
On the day
Wand or wireless interrogation
A programmer wand is placed over the device, or a wireless link is used. Painless — no needles, no imaging.
- 05
On the day
Battery, leads and thresholds
The physiologist reviews battery voltage and impedance, then tests lead sensing and pacing thresholds.
- 06
On the day
Stored electrograms reviewed
AF burden, VT/VF episodes and any delivered therapies (antitachycardia pacing, shocks) are inspected on-screen.
- 07
After
Written report and next steps
A written report — any programming changes, medication review, or electrophysiology consultation flagged clearly.
Typical end-to-end: 3–7 days. Urgent cases: same day.
What it shows
What a cardiac device check actually reveals.
A device interrogation answers a specific set of questions — is the hardware working, is the battery holding, and what has your heart been doing between visits.
-
Battery status (voltage, ERI)
Battery voltage and elective replacement indicator — the earliest sign a generator swap is due.
-
Lead impedance and thresholds
Sensing and pacing thresholds on each lead — the core check for lead integrity.
-
AF burden
Total time in atrial fibrillation since the last check — drives anticoagulation decisions.
-
VT / VF episodes
Any ventricular tachycardia or fibrillation events, with stored electrograms.
-
Antitachycardia pacing and shock delivery
Whether the device treated an arrhythmia with pacing or a defibrillation shock, appropriately or not.
-
CRT biventricular pacing percentage
The percentage of beats delivered biventricularly — the key CRT-response metric.
-
Sensing quality
How reliably the device sees intrinsic beats — under- or over-sensing changes therapy behaviour.
-
Red flag: elective replacement indicator (ERI) or lead failure — urgent electrophysiology review
Do not wait for a routine slot. Contact your electrophysiologist promptly.
Check types
Not all cardiac device checks are the same.
What each option on your referral is actually for.

Safety and eligibility
One of the safest tests in cardiology.
Device interrogation is exceptionally safe — the practical points are when a routine slot is right, when an urgent contact is right, and how to prepare for surgery or MRI.
-
Painless, non-invasive
A wand over your device, or a wireless link — no needles, no imaging, no discomfort.
-
Bring your device ID card
The card carries the manufacturer, model and lead details the physiologist needs.
-
Position on the couch
You lie or sit — that is the whole preparation. No fasting required.
-
Threshold testing sensations
Brief pacing tests may feel like a mild flutter for a few seconds — expected and safe.
-
ICD shocks are a medical emergency
If your ICD has delivered a shock, contact your electrophysiology team the same day.
-
MRI-conditional devices
Most modern devices are MRI-conditional. A device check is required before and after the scan.
-
Diathermy and surgery
Surgical diathermy can interfere with devices — programming changes may be needed pre-op.
-
Remote monitoring is not a shortcut
Remote alerts complement, not replace, scheduled in-clinic interrogation.
-
Bring prior device reports
Trend data across visits is what turns a snapshot into a decision — bring what you have.

Frequently asked
Everything we get asked about cardiac device checks.
Quick answers on how often, cost, remote monitoring, differences between pacemaker, ICD and CRT, and when to contact your team urgently.
-
How often should my cardiac device be checked?
In-clinic interrogation is typically every 6–12 months, with continuous remote monitoring in between. Loop recorders and ICDs generally sit at the more frequent end of that range.
-
What is the difference between a pacemaker, ICD and CRT?
A pacemaker treats bradycardia by pacing the heart when it is too slow. An ICD (implantable cardioverter-defibrillator) additionally detects and treats life-threatening ventricular arrhythmias with pacing or a shock. A CRT (cardiac resynchronisation therapy) device paces both ventricles together in selected heart-failure patients.
-
How much does a private cardiac device check cost in London?
A standard pacemaker interrogation is typically £180–£320 in our network; ICD and CRT checks are higher, and adding a consultant electrophysiology opinion raises the price. We confirm a firm figure within one working day.
-
Do I need a referral?
Most clinics accept self-referral for a device check. We can arrange a fast-track private GP or electrophysiology referral if a formal one is needed for insurance or onward pathway.
-
What is remote monitoring and do I need it?
Remote monitoring uses a bedside or bedside-app transmitter to send device data to your team overnight — often daily. It shortens the time between an event (a lead problem, an arrhythmia, low battery) and clinical action, and it is now standard for ICD and CRT devices.
-
When should I contact my team urgently?
Any ICD shock, new palpitations with dizziness or blackout, a remote-monitoring alert flagged as urgent, or symptoms suggestive of device infection (fever, redness or discharge at the pocket site). If you have chest pain or lose consciousness, call 999.

In practice, in London
What cardiac device checks looks like on the ground in London
With cardiac device checks, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. On the NHS, cardiac device checks typically sits behind a triage step and a wait that can stretch from a few weeks into months. In London’s private sector, the same appointment often lands within days. That speed matters when symptoms are disrupting work, sleep, or a plan you’d already committed to — and it’s the single most common reason people call us in the first place.
In practice, a private cardiac device checks appointment in London means a named consultant, a proper hour in the room (or the equivalent on a video call), and a report you can actually read. Most of the imaging suites and endoscopy units we use sit within a mile of Harley Street or in Chelsea and Fulham, and turnaround on findings is measured in days, not weeks. For cardiac device checks specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
The value of going through a concierge for cardiac device checks isn’t access — anyone with an insurer or a credit card can get a private appointment in London. The value is knowing which consultant reads this particular presentation best, which unit turns reports around fastest, and which pathway won’t hit a dead end if the findings point somewhere unexpected.
