Vedclass · Answer

(C) The correct answer is $(C)$.In the given diagram,the $P$-wave represents the electrical excitation (or depolarisation) of the atria,which leads to the contraction of both the atria.The $QRS$ complex represents the depolarisation of the ventricles,which initiates the ventricular contraction.The contraction starts shortly after $Q$ and marks the beginning of the systole.The $T$-wave represents the return of the ventricles from an excited to a normal state (repolarisation).The end of the $T$-wave marks the end of systole.
