Match List-I with List-II.

List - I
(ECG)		 List - II
(Electrical activity of heart)
(A) P-wave (I) Depolarisation of ventricles
(B) QRS complex (II) End of systole
(C) T wave (III) Depolarisation of atria
(D) End of T wave (IV) Repolarisation of ventricles

Choose the correct answer from the options given below :

  1. A
    A-(IV), B-(I), C-(III), D-(II)
  2. B
    A-(I), B-(IV), C-(III), D-(II)

Correct answer: D

An ECG (Electrocardiogram) is a test that measures the electrical activities of the heart. Each wave in an ECG represents a certain part of the heart's electrical activity:

  1. P wave : This wave occurs prior to the contraction of the atria (atrial contraction). It represents the depolarization of the atria.
  2. QRS complex : This is a series of three graph deflections seen on a typical electrocardiogram. It corresponds to the depolarization of the ventricles, which initiates the ventricular contraction.
  3. T wave : The T wave represents the repolarization (or recovery) of the ventricles.

By matching these descriptions with the options provided :

(A) P-wave - Depolarisation of atria (III)

(B) QRS complex - Depolarisation of ventricles (I)

(C) T wave - Repolarisation of ventricles (IV)

(D) End of T wave - End of systole (II)

So, the correct answer seems to be Option D : A-(III), B-(I), C-(IV), D-(II)
