Do you need an ECG after a GP consultation?

An ECG records the heart’s electrical signals through sensors placed on the skin. A GP may request it for chest discomfort, palpitations, breathlessness, dizziness, fainting, an irregular pulse, or a medicine and health review. It can provide useful information at one moment, but it does not explain every cause of symptoms. The result may be normal, may need discussion, or may lead to further assessment. The test itself does not decide whether treatment is needed; your clinician interprets it alongside your symptoms and examination.

Follow the appointment instructions and wear clothing that allows access to the chest, wrists, and ankles. Tell the clinician about medicines, heart conditions, pregnancy, implanted devices, and symptoms that occurred during activity or at rest. Ask whether the ECG is routine, how the result will be shared, and whether you should continue normal activities while waiting. Keep a note of when palpitations or discomfort occur, how long they last, and what you were doing at the time.

Seek emergency help for severe or persistent chest pain, severe breathlessness, fainting, blue or grey lips, or sudden weakness affecting one side of the body. Do not wait for a planned ECG if symptoms are rapidly worsening. For new or recurring palpitations, dizziness, or chest discomfort without emergency features, contact your GP or healthcare service promptly for advice.

Ask: What are you checking with the ECG? Should I have it during symptoms or at a particular time? When will I receive the result? Could another test be needed if the ECG does not explain what I feel?
