BATCH 1 – QUESTIONS 1–50
Question 1
An ECG shows a regular rhythm, HR 52 bpm, P waves before each QRS, PR interval 0.16 sec.
What is the rhythm?
A. Sinus tachycardia
B. Sinus bradycardia
C. Atrial fibrillation
D. First-degree AV block
Correct Answer: B. Sinus bradycardia
Rationale:
Heart rate <60 bpm with P waves preceding each QRS and normal PR interval indicates sinus
bradycardia.
Question 2
A patient’s ECG shows HR 102 bpm, regular rhythm, P waves present before each QRS. What is
the rhythm?
A. Sinus tachycardia
3
, Page 4 of 112
B. Supraventricular tachycardia
C. Ventricular tachycardia
D. Atrial flutter
Correct Answer: A. Sinus tachycardia
Rationale:
Rate >100 bpm with regular rhythm and normal P waves before QRS indicates sinus
tachycardia.
Question 3
ECG shows irregularly irregular rhythm, absent P waves, ventricular rate 110 bpm. What is the
rhythm?
A. Atrial fibrillation
B. Sinus arrhythmia
C. Junctional rhythm
D. Atrial flutter
Correct Answer: A. Atrial fibrillation
Rationale:
Absence of P waves with irregularly irregular QRS pattern indicates atrial fibrillation.
