Question

question 11 of 20 using the 1500 rule to calculate, what is the rate of this rhythm? 125 118 110 134

Explanation:

Step1: Recall 1500 rule

The 1500 rule for calculating heart - rate from an ECG is to divide 1500 by the number of small squares between two consecutive QRS complexes.

Step2: Count small squares

By observing the ECG, the number of small squares between two consecutive QRS complexes is 12.

Step3: Calculate rate

Rate=$\frac{1500}{12}=125$

Answer:

125
