An
electrocardiogram (EKG, ECG) is a test that measures the electrical signals
that control heart rhythm. The test measures how electrical impulses move
through the heart muscle as it contracts and relaxes.
During an
electrocardiogram, small pads or patches (electrodes) are attached to the skin on the
chest, arms, and legs. The electrodes are also connected to a machine that
translates the electrical activity into line tracings on paper. These tracings
are often analyzed by the machine and then carefully reviewed by a doctor for
abnormalities.
