Question 9 of 59

Which of the following are valid methods to calculate HR from an ECG?

Select one or more of the following:

The heart rate can be determined by identifying 6-seconds on the electrocardiogram paper and counting the number of QRS complexes in the 6-
second strip. The number of QRS complexes in 6 seconds multiplied by 10 gives the heart rate for 1 minute. HR = #QRS * 10
First, find a specific R wave that falls on a heavy black line. Then count off “300, 150, 100, 75, 60, 50” for each heavy black line that follows until the next R wave falls. To find the specific heart rate, determine the difference in rate between the dark lines that encircle the R wave (e.g., 300 − 150 = 150), and divide this number by 5 (the number of small boxes between the dark lines). Between 150 and 300, the distance between each small box is equivalent to 30 beats. Between 100 and 150, the distance between each small box represents 10 beats.
Count the number of large boxes between two R waves and divide this number into 300. HR = 300 / #LargeBoxes
Count the number of large boxes between the R waves, multiply this number by 5, and divide the product into 1500. HR = 1500 / (#LargeBoxes * 5)
The heart rate can be determined by identifying 6 seconds on the electrocardiogram paper and counting the number of QRS complexes in the 6-
second strip. The number of QRS complexes in 3-seconds multiplied by 10 gives the heart rate for 1 minute. HR = #QRS * 10
