An electrocardiogram (ECG) is a simple test that can be used to check your heart’s rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.
Patients must bring all previous diagnostic or operative reports and films if previous tests are done. If you are undergoing any medication that should be told to the doctor as it can change the test result. Fasting is not needed. You need to remove all the jewellery.
