Memorizing the sequence is just a quick way to determine the heart rate, but it's important to understand the big block method first so you know why those numbers of boxes equal those numbers of beats per minute. You can take the big block method and, instead of counting and dividing, you can just memorize the number sequence to determine the heart rate. We take 300 divided by 5 and get a heart beats per minute of 60.300 is the number of big boxes in one minute on an EKG.We count 5 big blocks between R waves on an EKG.A great example of this process is as follows: You then take 300, which is the number of big boxes in a minute on an EKG, and divide that by the number of big blocks counted. In the big block method we count the number of big blocks between R waves as opposed to small boxes. The big block method is very similar to the small box method explained above. We take 1,500 divided by 12 and get a heart rate of 125 beats per minute.1,500 is the number of small boxes in one minute on an EKG.We observe/count 12 small boxes between R waves on an EKG.

You are basically checking how many spaces-between-R-waves there are in a minute, and that's your heart rate! A great example of this process is as follows: The reason we use 1,500 is because there are 1,500 small boxes in one minute on an EKG. With the small box method, you count the number of small boxes between R waves, then divide 1,500 by that number, and that will give you the heart rate in beats per minute. If the rhythm is irregular, the six second strip method can be used. If the rhythm is regular, the small box method and big block method can be used. There are three ways to calculate a heart rate using an EKG. A regular atrial heart rhythm will have the same distance between P waves while an irregular rhythm will have varying distances between them. To determine if the atrial rhythm is regular vs irregular, we would measure the distance between P waves with a caliper. The atrial heart rhythm is represented by the P wave on an EKG. A regular ventricular heart rhythm will have the same distance between R waves while an irregular rhythm will have varying distances between them. To determine if the ventricular rhythm is regular vs irregular, we would measure the distance between R waves with a caliper. The ventricular heart rhythm is represented by the R wave on an EKG strip.

When checking to see if a heart rhythm is regular or irregular, we need to check both the atrial heart rhythm as well as the ventricular heart rhythm. Analyzing regular versus irregular heart rhythms
