MULTIPLE CHOICE QUESTIONS
Section 1: Basic ECG Interpretation
Question 1

What is the normal heart rate range for an adult?



A) 40-60 beats per minute

B) 60-100 beats per minute

C) 100-150 beats per minute

D) 80-120 beats per minute



Answer: B) 60-100 beats per minute



Rationale: Normal sinus rhythm in adults is defined as 60-100 bpm with regular rhythm and normal P
waves preceding each QRS complex.



Question 2

The P wave on an ECG represents:



A) Ventricular depolarization

B) Atrial depolarization

C) Ventricular repolarization

D) Atrial repolarization



Answer: B) Atrial depolarization

, Rationale: The P wave represents the electrical impulse traveling through the atria, causing atrial
contraction.



Question 3

What does the QRS complex represent?



A) Atrial depolarization

B) Atrial repolarization

C) Ventricular depolarization

D) Ventricular repolarization



Answer: C) Ventricular depolarization



Rationale: The QRS complex represents the electrical activation of the ventricles.



Question 4

The normal duration of a QRS complex is:



A) 0.04-0.10 seconds

B) 0.06-0.12 seconds

C) 0.12-0.20 seconds

D) 0.20-0.40 seconds



Answer: B) 0.06-0.12 seconds



Rationale: A QRS complex greater than 0.12 seconds is considered widened and may indicate a
conduction abnormality.
