Vertically the ECG graph measures the height amplitude of a given wave or deflection The standard calibration is 10 mm 10 small boxes equal to 1 mV On occasion Use the R R interval between two consecutive normal ECG waveforms Count the small boxes between the thick line before and after the 2nd R wave Use the scale below to determine the estimated reference range for heart rate
Each large box is 5 small boxes signifying 0 20 seconds or 200ms This becomes important to remember when determining the rate of regular rhythms The boxes and lines are also important in recognizing Each ECG is divided by large boxes and small boxes to help measure times and distances Each large box represents 0 20 seconds and there are five small boxes in each large box thus each small
