| Column I | Column II |
|---|---|
| A. P wave | I. Heart muscles are electrically silent. |
| B. QRS complex | II. Depolarisation of ventricles. |
| C. T wave | III. Depolarisation of atria. |
| D. T-P gap | IV. Repolarisation 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. QRS complex: - The QRS complex represents the depolarisation of the ventricles. - This matches with II.
