Analysis and structured report
- 01
Before
Consultation to define the question
A short, confidential form. Symptoms, timing, triggers, medications and what we need the recording to answer.
- 02
Before
Choose the modality
ECG, BP, glucose, sleep, pH, temperature or activity — matched to the clinical question, not a default.
- 03
During
Fit the device or patch
A brief clinic visit to place the monitor or apply the patch, with instructions for care and showering.
- 04
During
Diary of symptoms and activity
You keep a short log of symptoms, sleep, meals and activity — the anchor that makes the trace interpretable.
- 05
After
Return or wireless upload
Devices are returned to the clinic or upload data wirelessly at the end of the recording window.
- 06
After
Analysis by a specialist
A consultant in the relevant specialty reviews the trace against your diary.
- 07
After
Structured written report
A clear report, with the concrete next step — not just numbers.
Typical end-to-end: 1–3 weeks depending on modality. Urgent cases: same week.
The menu
The full menu of ambulatory monitoring.
Every modality worth considering, in one place — with what it’s actually for. The right choice is a match between the pattern you want to catch and the device that can catch it.
-
24-hour blood pressure (ABPM)
The reference standard for hypertension diagnosis — masked, white-coat and nocturnal patterns.
-
Ambulatory ECG (Holter / patch / loop)
Palpitations, syncope and paroxysmal atrial fibrillation, captured across days or weeks.
-
Continuous glucose monitoring (CGM)
Interstitial glucose every few minutes — hypos, post-prandial spikes and time in range.
-
Home sleep apnoea testing (WatchPAT)
A single-night home test for obstructive sleep apnoea — validated against in-lab polysomnography.
-
24-hour oesophageal pH
Objective quantification of acid reflux — the gold-standard test for refractory GORD.
-
Ambulatory temperature (fever workup)
Continuous skin or core temperature — useful in pyrexia of unknown origin.
-
Actigraphy (sleep-wake cycles)
A wrist-worn accelerometer that maps circadian rhythm, insomnia and shift-work disruption.
-
Red flag: any device recording life-threatening arrhythmia or hypoglycaemia — urgent same-day pathway
If the trace shows danger, we escalate the same day — not at the end of the recording window.
Next steps
What happens after the recording is done.
A recording is only useful if something follows it. These are the concrete next steps we build into every plan.
-
Data reviewed with a specialist
The trace is read by a consultant in the relevant specialty — cardiology, endocrinology, gastro or sleep.
-
Correlate with symptoms
Your diary is aligned to the trace — the moment matters as much as the number.
-
Adjust medication
Antihypertensives, insulin and other drugs are re-titrated to the ambulatory data, not the clinic reading.
-
Referral to the right specialty
Cardiology, endocrinology, gastroenterology or sleep medicine — routed based on what the recording shows.
-
Repeat monitoring for confirmation
A second recording confirms a borderline finding or checks the response to a treatment change.
-
Home telemonitoring for chronic disease
Ongoing remote monitoring for hypertension, diabetes or heart failure — with clinician oversight.
-
Integration with your health record
Reports and raw data are shared with your GP and specialists so nothing gets stranded.
-
Follow-up in 6–12 weeks
A review appointment to check the plan is working and decide whether to re-record.
Our vetted London network
A small panel of clinics, we picked them.
Partners across central, north, west and south London. Not listed publicly — introductions are made privately, once we understand your case.
Selection criteria
How we choose every clinic in our network.
-
Consultant specialists in cardiology, endocrinology, gastroenterology or sleep medicine
-
Validated, current-generation ambulatory devices with published accuracy data
-
Structured written report within 48–72 hours
-
Onward specialist pathway if the recording shows a red-flag finding
Red flags
When ambulatory data triggers an urgent pathway.
Ambulatory monitoring is safe — the important thing is knowing which patterns need action now, not a routine follow-up.
-
Life-threatening arrhythmia
Sustained VT, high-grade AV block or pauses on the trace trigger an urgent same-day cardiology pathway.
-
Severe hypertension
Ambulatory readings persistently ≥180/120 mmHg warrant urgent same-day medical review.
-
Severe hypoglycaemia
CGM readings below 3.0 mmol/L, particularly nocturnal, require same-day diabetes team review.
-
Severe sleep apnoea
AHI ≥30 with desaturations warrants urgent sleep specialist referral — not a routine slot.
-
Uncontrolled reflux with red flags
Reflux with dysphagia, weight loss or GI bleeding needs urgent endoscopy, not just pH monitoring.
-
Fever of unknown origin
Persistent unexplained pyrexia on ambulatory temperature monitoring requires structured infection and malignancy work-up.
-
Autonomic dysfunction
Orthostatic swings on ABPM or heart-rate variability abnormalities warrant neurology and cardiology input.
-
Uncontrolled diabetes
Time-in-range under 50% or HbA1c well above target triggers a same-week diabetes review.
-
Sudden loss of consciousness on the trace
Syncope with a captured arrhythmia is a same-day cardiology emergency, not a routine follow-up.
Reading your report
An ambulatory report can look intimidating. It isn’t.
Whatever the modality, the report keeps to the same four parts.
A quiet reminder
The report is written for your doctor, not for you — and that’s normal.
If you would like us to talk you through it before your follow-up, just ask.

Frequently asked
Everything we get asked about ambulatory monitoring.
Quick answers on modality choice, recording windows, when a repeat is needed, and when to go straight to A&E.
-
What is ambulatory monitoring?
Ambulatory monitoring uses wearable devices to record physiology — heart rhythm, blood pressure, glucose, sleep, oesophageal pH, temperature or activity — while you go about daily life. It captures patterns that a single clinic snapshot cannot.
-
How do I know which modality I need?
The modality is chosen from the symptom pattern. Palpitations point to an ambulatory ECG, borderline clinic BP points to ABPM, unexplained hypos or spikes to CGM, snoring and daytime sleepiness to a home sleep test, refractory reflux to 24-hour pH.
-
How long do you wear the device?
From 24 hours (ABPM, standard Holter, 24-hour pH) through 7–14 days (patch ECG, CGM) to weeks or months for implantable loop recorders. The recording window matches how often the pattern occurs.
-
Is ambulatory data really better than a clinic reading?
For blood pressure, glucose and arrhythmia, yes — ambulatory data is a substantially better predictor of outcomes than one-off clinic values, and is the reference standard in NICE guidance.
-
How quickly will I get results?
Most ambulatory reports return within 48–72 hours of the recording finishing. Patch ECG and pH studies can take 5–7 days because the raw data volume is much larger.
-
When should I go to A&E instead?
Any sudden chest pain, sudden neurological symptoms, severe breathlessness, collapse or a captured life-threatening arrhythmia is a 999 call — not a private appointment.

In practice, in London
Booking ambulatory monitoring overview privately in London — what actually happens
With ambulatory monitoring overview, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Waiting lists on the NHS for ambulatory monitoring overview vary widely by borough and by how the GP letter reads. Privately in London, we can normally offer a slot inside the same week, sometimes within 48 hours if there’s a cancellation. The difference isn’t clinical quality — the consultants are frequently the same faces you’d see on the NHS — it’s the calendar.
Once you’re in the private system for ambulatory monitoring overview, the pace picks up noticeably. Consultant slots run to time, imaging is usually available in the same building or a short walk away, and the report comes back typed and detailed. It’s the coordination that tends to feel different — one person on the other end of the phone, not a switchboard. For ambulatory monitoring overview specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
Where a good concierge earns its keep is in the matching. There are dozens of consultants in London who see ambulatory monitoring overview — but not all of them are the right fit for every case. We narrow it down based on subspecialty, insurer coverage, the specific question being asked, and whether continuity into treatment matters. The right first appointment saves you from repeating yourself later.
