Text Solution

Verified by Experts

The correct Answer is:
A
Obviously, by counting the number of QRS complexes that occur in a given time period, one can determine the heart beat rate of an individual.
Since the ECGs obtaineed from different individuals have roughly the same shape for a given lead configuration, any deviation from this shape indicates a possible abonrmality or disease. Hence, it is of a great clinical significance.
