Chest pain can be worrying, but it does not always come from the heart. If you are searching for help with chest pain in London, a clinician can assess your symptoms and decide whether you need tests such as an electrocardiogram (ECG), blood tests or an echocardiogram. The right investigation depends on your symptoms, medical history and examination; an echocardiogram is useful for some questions, but it cannot diagnose every cause of chest pain.
When chest pain may be an emergency
Call 999 if you have sudden or severe chest pain, especially if it feels like pressure, squeezing or tightness, does not go away, or spreads to your arm, neck, jaw, back or stomach. Chest pain with breathlessness, sweating, nausea, light-headedness or collapse can also require emergency help. Do not drive yourself to hospital if you think you may be having a heart attack.
If your symptoms are not immediately life-threatening but you are unsure what to do, contact NHS 111 or seek prompt medical advice. New, persistent or worsening chest pain should not be ignored or self-diagnosed.
What can cause chest pain?
Chest discomfort may come from the heart, lungs, muscles, ribs, digestive system or other causes. Examples include angina, inflammation around the heart, acid reflux, a chest infection, or strain in the chest wall. Anxiety can also be associated with chest symptoms, but it is important not to assume anxiety is the cause before appropriate assessment.
The way pain feels can offer clues, but it cannot reliably identify the cause by itself. A clinician will consider when the pain started, how long it lasts, what brings it on or eases it, and whether it comes with other symptoms. They may also ask about your health, medicines, smoking, and family history.
How chest pain is assessed in London
An assessment usually starts with a conversation about your symptoms and relevant medical history, followed by a physical examination. Depending on the situation, a clinician may recommend an ECG, blood tests or imaging. Some tests are time-sensitive, so suspected emergencies need urgent hospital assessment rather than a routine appointment.
For ongoing or recurring symptoms, a cardiologist may consider whether the heart is involved and which investigations are appropriate. These might include an echocardiogram, an exercise or stress test, or imaging to look at the heart’s blood supply. The choice depends on the clinical question; no single test is right for every person.
What is an echocardiogram?
An echocardiogram, often called an echo, is an ultrasound scan of the heart. It uses sound waves to create moving images. A standard transthoracic echocardiogram is performed by placing a probe on the chest, usually with gel to help it make contact with the skin.
The scan can help assess the heart’s size and structure, how well its chambers pump, how the valves move, and the direction of blood flow. It may also show fluid around the heart or features of some structural heart conditions. The findings are interpreted alongside symptoms, examination results and other tests.
Can an echocardiogram explain chest pain?
Sometimes. An echocardiogram may help when a clinician wants to investigate a suspected problem with the heart muscle, valves or structure. It can also provide information about how the heart is functioning.
However, an echo does not directly show whether the arteries supplying the heart are narrowed in the way a coronary scan might. It also cannot rule out every heart-related cause of chest pain. A normal result is reassuring about the features the scan assesses, but it does not automatically explain symptoms or rule out coronary artery disease. Further tests may be needed if the clinical assessment suggests them.
What happens during an echocardiogram?
For a standard transthoracic scan, you will usually lie on an examination couch while the sonographer or clinician moves a probe across your chest. You may be asked to change position or briefly hold your breath to obtain clear images. The test is generally painless, though the probe may press against the chest. It does not use X-rays.
The length of an appointment and how results are shared can vary by provider and the type of scan. Ask the clinic what to expect, whether you need to prepare, and who will explain the findings. If you have particular concerns about the procedure, raise them before the scan begins.
Preparing for an appointment about chest pain
A few notes can help you describe your symptoms clearly. Consider recording when the pain occurs, how long it lasts, what it feels like, whether activity or rest changes it, and any associated symptoms. Bring a list of your medicines and relevant medical history, if available.
- Describe the location and character of the discomfort, including whether it spreads elsewhere.
- Explain what you were doing when it began and what seems to bring it on or ease it.
- Mention breathlessness, palpitations, nausea, dizziness or other symptoms.
- Share details of previous heart tests and any known health conditions.
Do not wait for a scheduled appointment if chest pain becomes severe, persistent or is accompanied by emergency warning signs. Seek urgent help instead.
Choosing the next step
The most useful next step depends on how you feel now. Sudden severe symptoms may require emergency care. For new or recurring pain that is not an emergency, contact an appropriate healthcare professional for advice and assessment. A cardiologist can help determine whether the symptoms may be heart-related and whether an echocardiogram or another test is suitable.
If you are considering an echocardiogram in London, ask what clinical question the scan is intended to answer, who will review the result, and what follow-up is recommended. Clear explanations can help you understand what the test can—and cannot—tell you.
Frequently Asked Questions
Does every person with chest pain need an echocardiogram?
No. The appropriate tests depend on the symptoms and clinical assessment. An echocardiogram is useful for examining heart structure and function, but it is not necessary or sufficient for every chest-pain investigation.
Can a normal echocardiogram rule out a heart attack?
No. An echocardiogram alone cannot rule out a heart attack. Suspected heart attacks require urgent assessment, which may include an ECG and blood tests. Call 999 for symptoms that could be an emergency.
Is an echocardiogram painful?
A standard echocardiogram is usually painless. The probe is moved over the chest with gel, and there may be some pressure while images are taken.
How is an echocardiogram different from an ECG?
An ECG records the heart’s electrical activity using electrodes on the skin. An echocardiogram uses ultrasound to create images of the heart’s structure and movement. They provide different information and may both be used during an assessment.
When should I call 999 for chest pain?
Call 999 for sudden or severe chest pain, pain that does not go away or spreads to other areas, or chest pain accompanied by symptoms such as breathlessness, sweating, nausea, light-headedness or collapse.
Can I book an echocardiogram without a clinical assessment?
Whether a scan can be booked directly depends on the provider. It is important that a qualified clinician determines whether the test is appropriate and explains the result in the context of your symptoms.
