Question

Match List I with List II:

List I		List 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.

Choose the correct answer from the options given below:

• A. A-I, B-III, C-IV, D-II
• B. A-III, B-II, C-IV, D-I
• C. A-II, B-III, C-I, D-IV
• D. A-IV, B-II, C-I, D-III

Answer 1

The Correct Option is B

- P wave represents the depolarization of atria, so it corresponds to III.

- QRS complex represents the depolarization of ventricles, so it corresponds to II.

- T wave represents the repolarization of ventricles, so it corresponds to IV.

- T-P gap represents the period where heart muscles are electrically silent, so it corresponds to I.

Thus, the correct match is: A- III, B- II, C- IV, D- I
