Electrocardiogram (ECG)

An electrocardiogram (ECG) is a test that can record the rhythm and electrical activity of your heart to find out if it’s healthy.

An ECG measures the electrical signals that cause your heart to beat and can identify abnormalities in the electrical wiring of the heart. It is often used to detect abnormalities in the heart structure or when your doctor suspects that you have angina.

During the test, a number of wires are connected to your arms, legs and chest and these pick up the electrical signals which are then recorded and printed out for the doctor to interpret
