36. A QRS complex is the ventricular contraction of the heart. There is one QRS complex per beat. So, since the person's heart rate is 72 bpm, divide it by 2.

How can you calculate heart rate on ecg of arterial fibrilation?
Hello,1. You measure in the distance in mm from from one R wave to the next R wave.2. Then multiply that number by 0.04 (at a normal chart speed of 25mm/sec each mm = 0.04 sec). Answer = R-R interval in seconds.3. Divide 60 by the answer to 2. (60 seconds in a minute)Answer = HR in bpmHope this helps :)Hi,So the above method is fine if the rate is regular (though I prefer to divide the 300 by the R-R interval), but to determine the rate in atrial fibrillation:1. Count out 6 seconds (ie 30 big squares)2. Count the number or QRS complexes in that period3. Times the number of QRS complexes by 10.Answers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.comAnswers.com

How do you determine the heart rate on an EKG strip?
Remember a small box is 0.04seconds and the larger box is 0.2seconds For regular rhythms the heart rate is calculated as follows: 1500 divided by the number of small squares between two consecutive R waves (works better for faster heart rates) 300 divided by the number of large squares between two consecutive R waves (only works with slower heart rates) For irregular rhythms the heart rate can be calculated by multiplying the number of QRS complexes on the ECG by 6 (recall that at standard paper speed of 25 mm/s each ECG records 10 seconds of activity)
