Electrocardiography (ECG) is most frequently performed in patients with chest pain, history of heart diseases, or suspected heart diseases.
ECG is also performed in patients with suspected heart rhythm disorders, elevated blood pressure and heart failure.
ECG is informative not only for elderly patients, but also young patients, in whom heart diseases of atherosclerotic origin are comparatively less frequent, while heart defects, heart rhythm disorders and elevated blood pressure are more common.
National Health Service (NHS), insurance company and paid services are available.
