Calculating Heart Rate - note strips on pretest are longer than 6 seconds.
Table for Small Box Method
To calculate the heart rate, count the number of 0.04 squares (or small boxes) between two QRS complexes (1500 divided
divid by X = HR)
Small Boxes 9 = 168 14 = 107 19 = 79 24 = 63 29 = 52 34 = 44 39 = 38 44 = 34
