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).
A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.To measure your heart rate, simply check your pulse. Place your index and third fingers on your neck to the side of your windpipe.hen you feel your pulse, count the number of beats in 15 seconds. Multiply this number by 4 to calculate your beats a minute. Keep in mind that many factors can influence heart rate, including: 1  Activity level. 2  Fitness level. 3  Air temperature. 4  Body position (standing up or lying down, for example). 5  Emotions.
