E.C.G | E.K.G An ECG (electrocardiogram) is a test that measures the electrical activity of the heart. In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease. The information obtained from an electrocardiogram can be used to diagnose different types of heart disease. It may also be useful for seeing how a patient is responding to treatment. It is a good idea to have an ECG in the case of symptoms such as dyspnoea (difficulty in breathing), chest pain (angina), fainting, palpitations or when someone can feel that their own heart beat is abnormal.
An ECG may appear normal even in the presence of significant heart disease. Thus, for a full assessment of the heart, other tests may be needed.
