What is the definition or description of: electrocardiogram?
A doctor has provided 1 answer
See below: Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface can indicate underlying disease.
