Match List I with List II:
| Column I | Column II |
|---|---|
| A. P-wave | I. Beginning of systole |
| B. Q-wave | II. Repolarisation of ventricles |
| C. QRS complex | III. Depolarisation of atria |
| D. T-wave | IV. Depolarisation of ventricles |
To solve this problem, we need to match the items in List I with the appropriate descriptions in List II. Let's analyze each item:A. P-wave: - The P-wave represents the depolarisation of the atria. - This matches with III.B. Q-wave: - The Q-wave is part of the QRS complex, which marks the beginning of ventricular depolarisation and the start of systole.
