Best answer

Answer: 2. A-III, B-I, C-IV, D-II

Key idea: Link each ECG wave to the heart event.

  • P wave: depolarisation of the atria (III).
  • Q wave: beginning of systole (I).
  • QRS complex: depolarisation of the ventricles (IV).
  • T wave: repolarisation (return to normal) of the ventricles (II).

A-III, B-I, C-IV, D-II is option 2.
