Vedclass · Answer

(B) The heart beat rate of an individual can be determined by counting the number of $QRS$ complexes that occur in a given time period.Each $QRS$ complex represents the depolarization of the ventricles,which initiates the ventricular contraction (systole).Since one $QRS$ complex corresponds to one heartbeat,the total number of these complexes in a specific timeframe allows for the calculation of the heart rate.
