Match List I with List II (ECG components):

- AA-I, B-II, C-III, D-IV
- BA-II, B-I, C-IV, D-III
- CA-III, B-II, C-IV, D-I
- DA-I, B-III, C-II, D-IV
Solution & Step-by-step Explanation
P-wave: Depolarization of the atria.QRS complex: Depolarization of the ventricles.T-wave: Repolarization of the ventricles.T-P gap: Period between end of T and beginning of P, where heart is in diastole (electrical silence).Correct Match: A-I, B-II, C-III, D-IV.
