EKG

Electrocardiography (ECG or EKG from the German Elektrokardiogramm) is a transthoracic (across the thorax or chest) interpretation of the electrical activity of the heart over a period of time, as detected by electrodes attached to the outer surface of the skin and recorded by a device external to the body. The recording produced by this noninvasive procedure is termed as electrocardiogram(also ECG or EKG). An electrocardiogram (ECG) is a test that records the electrical activity of the heart. (adapted from wikipedia)
