The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10. For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70). ...
Determine the number of boxes in one minute. Fifteen large boxes equals three seconds.The EKG graph paper has markings between each segment of 15 large boxes to indicate the 3 second intervals.Attain a 6 second EKG strip (30 large boxes) and multiply the number of p-waves in the six seco...
If a patient’s heart rhythm isirregular,the first heart rate calculation method doesn’t work (as the R-R interval differs significantly throughout the ECG). As a result, you need to apply a different method: Count the number of complexes on the rhythm strip (each rhythm strip is typical...
