Can You See a Private GP While Registered with the NHS?
We get asked all of the time, “Is it OK that I have an NHS GP?” It absolutely is! It’s
An echocardiogram, often referred to as an “echo,” is a non-invasive, ultrasound-based test that provides a detailed image of your heart’s structure and function.
Using sound waves, this test allows our medical professionals to see real-time images of your heart’s chambers, valves, and blood flow, ensuring we get a comprehensive picture of your cardiovascular health.
It is different from an ECG (electrocardiogram), which measures the electrical activity of the heart.
An echocardiogram can be crucial for diagnosing and monitoring a range of heart conditions. It helps in assessing heart valve issues by evaluating valve function and detecting conditions such as stenosis or regurgitation.
The test is also important for evaluating heart failure, as it provides insights into the heart’s pumping efficiency and overall function. Additionally, echocardiograms are used to identify congenital heart defects, which are structural abnormalities present from birth.
They can also detect and assess cardiac tumours, identifying any abnormal growths within the heart. Finally, an echocardiogram is useful for checking pericardial effusion, which involves fluid accumulation around the heart.
Depending on your symptoms or conditions, different types of echocardiograms may be recommended. The Transthoracic Echocardiogram (TTE) is the most common, using a chest transducer to create detailed images of the heart’s chambers and valves. The Transoesophageal Echocardiogram (TEE) provides clearer images of areas behind the heart by inserting a flexible tube with a transducer into the oesophagus.
A Stress Echocardiogram combines an echocardiogram with a stress test, such as exercise, to assess heart performance under stress and diagnose coronary artery disease. The Doppler Echocardiogram measures blood flow speed and direction to evaluate heart valve function and detect issues like regurgitation or stenosis, whereas a 3D Echocardiogram offers a three-dimensional view of the heart’s structures, and a Fetal Echocardiogram examines the heart of an unborn baby during pregnancy to identify congenital defects.
Each type provides specific insights based on individual needs and conditions.
With detailed insights into your heart’s condition, an echocardiogram allows for personalised care, tailoring treatment plans to your specific needs. Ongoing monitoring is another advantage, enabling you to track the progression of existing heart conditions and evaluate the effectiveness of treatments.
Ultimately, an echocardiogram provides peace of mind, giving you confidence in your heart health through comprehensive, real-time imaging.
After your echocardiogram, there is generally no special care required. You can resume normal activities immediately. Here is what to keep in mind:
Use our online booking engine or book your appointment by giving us a call.
On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly doctors or trained clinicians.

When preparing for your echocardiogram, wear comfortable clothing to ensure ease during the procedure. Follow any specific instructions regarding eating or drinking beforehand to ensure accurate results. Be prepared to remove clothing above the waist, as this will allow the technician to access the area needed for the test. It is also important to inform the technician about any medications you are taking or any health conditions you have. Throughout the test, try to relax and breathe normally to help obtain the clearest images possible.

During the echocardiogram, a technician will first apply gel to your chest. This gel helps to ensure a good connection between the transducer and your skin. A wand-like device, known as a transducer, is then moved over your chest to capture images. The transducer uses sound waves to create detailed images of your heart’s structure and function. The procedure is painless and typically takes about 30 – 60 minutes to complete.

In many cases, the technician cannot provide results directly. Your doctor will review the images and discuss the findings with you during a follow-up appointment. You can resume normal activities immediately unless advised otherwise. If you underwent a TEE (transesophageal echocardiogram) and were sedated, avoid operating heavy machinery or making important decisions until the effects of the sedative wear off.

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.Posted on Trustindex![]()

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.Posted on Google![]()

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.Posted on Google![]()

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.Posted on Google![]()

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.Posted on Google![]()

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.Posted on Yell![]()

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.Posted on Yell![]()

i have used these guys many times in the last 6 years and its always very fast and professional. most tests are done in 24hours and they call you to explain the results. recommended if you gp (like mine) gives you an appointment in 4 weeks time.
