Q.

Match List I with List II:

List IList II
A. P waveI. Heart muscles are electrically silent
B. QRS complexII. Depolarisation of ventricles
C. T waveIII. Depolarisation of atria
D. T-P gapIV. Repolarisation of ventricles

Choose the correct answer from the options given below:

  1. A

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

  2. B

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

  3. C

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

  4. D

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

Solution

In an ECG: P wave records atrial depolarisation (A-III); QRS complex records ventricular depolarisation (B-II); T wave records ventricular repolarisation (C-IV); the T-P gap is the period between consecutive cardiac cycles when the heart muscles are electrically silent (D-I).
