ECG in Kingston
A 12 lead ECG at KONCEPT® Medical Clinic in Kingston costs £119, takes about 10 minutes and includes a report from our cardiologist, Dr Ameer Al-Bassam. No GP referral is needed if you pay for yourself.
An ECG (electrocardiogram) is a quick, painless recording of the electrical signals that make your heart beat. Ten small sticky patches on your chest, arms and legs pick up those signals, and the machine turns them into 12 views of your heart, which is why it is called a 12 lead ECG.
It shows your heart rate and rhythm, and it can show signs of strain on the heart muscle, a problem with the heart’s wiring, or a heart attack in the past. Because it records only a few seconds, symptoms that come and go may need a longer recording with a Holter monitor.
You might need an ECG if you have palpitations, chest pain, dizziness or breathlessness, or if a doctor wants a baseline check of your heart before treatment, sport or a work medical.
A racing, pounding, fluttering or irregular heartbeat, or a feeling of missed beats.
Chest pain or tightness that comes and goes and is not happening now. If you have chest pain now, call 999 instead.
Dizzy spells, light headedness, fainting in the past, or getting out of breath more easily than before.
Some medicines, sport, travel and work medicals need a baseline ECG, and so do people with high blood pressure or diabetes.
An ECG at KONCEPT® takes about 10 minutes from start to finish. You lie on a couch, the patches are placed, and the recording itself takes a few minutes while you lie still.
Your ECG is reported by our cardiologist, Dr Ameer Al-Bassam, and you receive a written report, usually within a few working days. If anything on your ECG needs attention sooner, we contact you without waiting for the written report. With your consent, we send a copy to your NHS GP.
A normal ECG is reassuring, but it shows only the moment it was recorded. If your symptoms come and go, a Holter monitor records every heartbeat for longer, and if the cardiologist needs to see the structure of your heart and its valves, an echocardiogram is the test that shows it.
An ECG is the first test for most heart symptoms. A Holter monitor records your rhythm for longer, 24 hour blood pressure monitoring checks your blood pressure through a normal day, and an echocardiogram looks at the heart itself. If you are not sure which you need, start with a cardiology consultation.

Many private medical insurance policies cover an ECG when it is needed to investigate symptoms, if your policy includes outpatient cover. For your insurer to pay, the clinic and the cardiologist usually both need to be recognised by that insurer, and most insurers ask for a GP or open referral and a pre authorisation number first.
Please call 020 8129 1011 with your insurer and policy number before you book, so we can confirm your cover in writing. If you pay for yourself, no GP referral is needed.
Every ECG recorded at KONCEPT® is reported by Dr Ameer Al-Bassam, a specialist and interventional cardiologist on the GMC Specialist Register for cardiology, who also works in the NHS at Chelsea and Westminster Hospital NHS Foundation Trust.

About 10 minutes in clinic. The recording itself takes only a few minutes while you lie still.
No. An ECG only records the electrical signals from your heart through sticky patches on your skin. Nothing passes into your body. Peeling the patches off can feel like removing a plaster.
Yes. There is no need to fast before a resting ECG. Avoid body lotion, oil or talc on your chest on the day, as the patches need clean, dry skin.
You receive a written report from our cardiologist, usually within a few working days. If anything needs attention sooner, we contact you without waiting for the written report.
Yes. An ECG shows your heart’s electrical activity only while it is being recorded, so a rhythm problem that comes and goes, or a problem with a heart valve, can be missed. That is why the cardiologist may suggest a Holter monitor or an echocardiogram as well.

A borderline result means a small change that is not clearly normal or abnormal, and it is common in healthy people. Our cardiologist looks at it alongside your symptoms and history, and tells you whether anything else is needed, such as a repeat ECG or an echocardiogram.
Yes. NICE guidance recommends a 12 lead ECG for people diagnosed with high blood pressure, to check whether it has affected the heart.
Often, yes. An ECG can show changes left by a previous heart attack, although a normal ECG does not rule one out.
A 12 lead ECG records your heart for a few seconds while you lie still in the clinic. A Holter monitor records every heartbeat for 24 hours to 7 days while you go about your life, so it can catch symptoms that come and go.
