Question

count the QRS complexes in a 6 second strip & multiply by 10 to estimate rate for 1 minute (3 seconds = 15 large boxes)

Answer 1

When the frequency between the QRS complexes increases, it indicates that the heart rate (pulse) is increasing. To estimate the heart rate, count the number of QRS complexes in a 6-second strip and multiply by 10 to estimate the rate for 1 minute.

Step-by-step explanation:

The heart rate, or pulse, is said to be increasing when the interval between QRS complexes becomes more frequent. The number of QRS complexes in a 6-second strip is counted, and the result is multiplied by 10 to get the heart rate estimate for one minute.

For instance, multiplying the number of QRS complexes in a 6-second strip by 10 yields an estimated rate of 60 beats per minute.
