The amplitude (distance of positive peaks and negative nadirs from the baseline) and duration (width from beginning or onset to end or offset) of ECG waves are measured by visual reference to the grid lines on the ECG recording paper, or by use of devices including a magnified measuring loupe or a clear plastic ruler on calipers. Use of such devices has been demonstrated to improve coding repeatability.
