Electrodes on the skin of a 66 year old patient undergoing an ECG (electrocardiogram). ECG uses electrodes to measure the electrical activity of the heart during the pumping of its chambers, and records this activity as an electrical wave on a screen or sheet of paper. Electrocardiography is a useful tool for the diagnosis of heart disease. The waves of an ECG trace can reveal the nature and location of many cardiac disorders. | |
