ECG

An electrocardiogram (ECG) is a simple, non-invasive test that records the electrical activity of the heart.

An ECG can help diagnose certain heart conditions, including abnormal heart rhythms and coronary heart disease (heart attack and angina).

A doctor may recommend an ECG if you are experiencing symptoms like chest pain, breathlessness, dizziness, fainting or a feeling of your heart racing, fluttering, thumping or pounding in your chest (palpitations).
