ECG stands for Electrocardiography, which is a non-invasive diagnostic test that records the electrical activity of the heart. This electrical activity, which is caused by electrical charges created by the heart as it beats, is picked up by the electrodes that are placed over the skin. It is useful to assess the heart rhythm, identify any heart disease, and for evaluation of cardiac efficiency.
