[b] QRS Complex (ii) Repolarisation of ventricles
[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.

Options:

A) [a] (iI) [b] (i) [c] (v) [d] (iii)

B) [a] (ii) [b] (iii) [c] (v) [d] (iv)

C) [a] (iv) [b] (i) [c] (ii) [d] (iii)

D) [a] (iv) [b] (i) [c] (ii) [d] (v)

Answer:

Correct Answer: C

Solution:

  • To match the columns correctly, let’s understand the significance of each wave in an electrocardiogram (ECG):
  • P-wave: Represents the depolarization of the atria.
  • QRS Complex: Represents the depolarization of the ventricles.
  • T-wave: Represents the repolarization of the ventricles.
  • Reduction in the size of T-wave: Can indicate coronary ischemia.

Now, let’s match Column-I with Column-II:

  • [a] P-wave matches with (iv) Depolarisation of atria.
  • [b] QRS Complex matches with (i) Depolarisation of ventricles.
  • [c] T-wave matches with (ii) Repolarisation of ventricles.
  • [d] Reduction in the size of T-wave matches with (iii) Coronary ischemia.
