Question

Match List I with List II:

List I
A. P wave
B. QRS complex
C. T wave
D. T-P gap

List II
I. Heart muscles are electrically silent.
II. Depolarisation of ventricles.
III. Depolarisation of atria.
IV. Repolarisation of ventricles.

Choose the correct answer from the options given below:
(1) A-I, B-III, C-IV, D-II
(2) A-III, B-II, C-IV, D-I
(3) A-II, B-III, C-I, D-IV
(4) A-IV, B-II, C-I, D-III

Accepted Answer

Correct Answer: B — A-III, B-II, C-IV, D-IStep-by-step Solution:ECG (electrocardiogram) waves represent electrical events of the cardiac cycle:P wave: Depolarisation of the atria. Hence, A matches with III (Depolarisation of atria).QRS complex: Depolarisation of the ventricles (also masks atrial repolarisation). Hence, B matches with II (Depolarisation of ventricles).T wave: Repolarisation of the ventricles. Hence, C matches with IV (Repolarisation of ventricles).T-P gap: The interval between the T wave and the next P wave, during which the heart muscles are electrically silent (diastole). Hence, D matches with I (Heart muscles are electrically silent).Thus, A-III, B-II, C-IV, D-I corresponds to option B.Key Concepts: ECG waveform interpretation: P wave (atrial depolarization), QRS (ventricular depolarization), T wave (ventricular repolarization), T-P gap (electrical diastole).
