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.

Step-by-step solution

The P wave in an ECG represents the electrical excitation or depolarisation of the atria, which leads to the contraction of both atria. Thus, Statement-I is incorrect. The T wave represents the return of the ventricles from an excited state to a normal state, which is known as repolarisation. Thus, Statement-II is correct. Therefore, Statement-I is wrong but Statement-II is correct. Answer: Statement-I is wrong but Statement-II is correct.
