Vedclass · Answer

(C) Step $1$: The '$P$' wave in an $ECG$ represents the electrical excitation or depolarisation of the atria, which leads to the contraction of both atria.Step $2$: The '$QRS$' complex represents the depolarisation of the ventricles, which initiates the ventricular contraction.Step $3$: The '$T$' wave represents the return of the ventricles from an excited to a normal state, i.e., repolarisation of the ventricles.Step $4$: Therefore, Statement $I$ is incorrect because '$P$' wave represents atrial depolarisation, and Statement $II$ is correct because '$T$' wave represents ventricular repolarisation.

Consider the following statements with respect to $ECG$ [Electrocardiogram] and choose the correct answer.
Statement $I$ : '$P$' wave represents the depolarisation of ventricles.
Statement $II$ : '$T$' wave represents the repolarisation of ventricles.
