What does ECG mean?

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.
