ECG waveforms and their significance
-
Match List-I (ECG) with List-II (Electrical activity of heart).
Pick the matching item from Column II for each row.
Column I
- A. P-wave
- B. QRS complex
- C. T wave
- D. End of T wave
Column II
- I. Depolarisation of ventricles
- II. End of systole
- III. Depolarisation of atria
- IV. Repolarisation of ventricles
Correct answer: A → III, B → I, C → IV, D → II
P-wave represents depolarisation of the atria (A-III); QRS complex represents depolarisation of the ventricles (B-I); T wave represents repolarisation of the ventricles (C-IV); the end of the T wave marks the end of systole (D-II).
Differential white blood cell count
-
Match List-I with List-II.
Pick the matching item from Column II for each row.
Column I
- A. Eosinophils
- B. Lymphocytes
- C. Neutrophils
- D. Monocytes
Column II
- I. 6-8%
- II. 2-3%
- III. 20-25%
- IV. 60-65%
Correct answer: A → II, B → III, C → IV, D → I
Eosinophils make up 2-3% of white blood cells (A-II); Lymphocytes make up 20-25% (B-III); Neutrophils make up 60-65% (C-IV); Monocytes make up 6-8% (D-I).
