1.	The given figure is the ECG of a normal human. Which one of its components is correctly interpreted below ? A. Peak T-initiation of total cardiac contractionB. Peak T-initiation of total cardiac contractionC. Peaks P and R-systole end diastole blood pressureD. Peak T-initiation of left atrial contraction only
Answer» Correct Answer - 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.
