Count the number of QRS complexes in one continuous lead where cardiac activity was monitored for the whole 10 seconds or in contiguous leads encompassing 10 seconds of cardiac activity. Multiply this number by 6 (10 x 6 = 60 seconds = 1 minute) to obtain the number of heartbeats per minute or the average heart rate.ow to determine the heart rate when it is lower than 50 beats per minute (regular rhythm): 1  Count the number of large squares between two successive R waves. 2  Divide 300 by the number of large squares obtained in #1. 3  The quotient is the heart rate (cardiac cycles per minute or heart beat per minute).
Calculate Your Average Resting Heart Rate. 1  Find your pulse with your fingers, not your thumb, while lying in bed before you get up in the morning. 2  Count your pulse for 15 seconds and multiply by four, or 30 seconds and multiply by two. Example: If you count 32 beats in 30 seconds, your resting heart rate is 64 BPM (32 x 2). Record your heart rate for five days. Add the five days' resting heart rates together and divide by five to find your average resting heart rate.
