(c) T - wave | (iii) Coronary ischemia

(d) Reduction in the size of T - wave | (iv) Depolarisation of atria

| (v) Repolarisation of atria

Select the correct option.

1. (a) (iv) (b) (i) (c) (ii) (d) (iii)

2. (a) (iv) (b) (i) (c) (ii) (d) (v)

Best answer

Answer: 1. (a) (iv) (b) (i) (c) (ii) (d) (iii)

Link each ECG part to the cardiac event.

  • P-wave: depolarisation of the atria, so (iv).
  • QRS complex: depolarisation of the ventricles, so (i).
  • T-wave: repolarisation of the ventricles, so (ii).
  • A reduced T-wave points to coronary ischemia, so (iii).

This matches option 1.
