(B) In an electrocardiogram $(ECG)$,the $P$-wave represents the electrical excitation (depolarization) of the atria,which leads to the contraction of both the atria.The $QRS$ complex represents the depolarization of the ventricles,which initiates the ventricular contraction.The $T$-wave represents the return of the ventricles from an excited state to a normal state (repolarization). The end of the $T$-wave marks the end of systole.Therefore,the $T$-wave is the repolarization wave.
