Introduction
An echocardiogram is an ultrasound scan of the heart. It helps assess heart muscle function, valves and the size of the chambers, and may be recommended when symptoms or an ECG suggest it would add useful information.
What the scan can and cannot show
The scan shows how the heart is pumping, whether valves are opening and closing normally, and whether the chambers or heart muscle look unusual. It can be particularly useful for breathlessness, a murmur, heart failure assessment or selected rhythm concerns.
It does not directly show the heart’s electrical activity or reliably exclude all artery problems. We explain how the result fits with other tests and whether any additional investigation is necessary.
Key points
- It is non-invasive and does not use radiation.
- The scan is usually performed with you lying on your side.
- Results are considered together with symptoms, ECG and other tests.
Patient note
“An echocardiogram is valuable when it answers a structural question. It is not needed simply because a symptom is worrying.”

FAQ
Is an echocardiogram painful?
No. The probe is moved over the chest with ultrasound gel; there may be mild pressure only.
