, Q1. Normal PR interval?
A) 0.12-0.20 sec
B) 0.04-0.12
C) 0.20-0.40
D) <0.04
Correct: A
Rationale: PR 0.12-0.20 sec (3-5 small squares) AV conduction.

Q2. Normal QRS?
A) <0.12 sec
B) 0.12-0.20
C) >0.20
D) 0.20-0.40
Correct: A
Rationale: QRS <0.12 narrow supraventricular, >=0.12 wide ventricular.

Q3. Sinus bradycardia?
A) <60 with P before each QRS
B) >100
C) No P
D) Irregular
Correct: A
Rationale: Sinus brady <60 regular P before QRS PR normal.

Q4. AFib?
A) Irregularly irregular no P fibrillatory
B) Regular
C) Sawtooth
D) P with QRS
Correct: A
Rationale: AFib irregularly irregular no P fibrillatory baseline atrial 350-600.

Q5. Atrial flutter?
A) Sawtooth F waves 300 atrial
B) Irregular
C) Wide
D) No flutter
Correct: A
Rationale: Flutter sawtooth F waves atrial 250-350 typically 300.

Q6. First-degree AV block?
A) PR >0.20 constant 1:1
B) PR <0.12
C) Dropped
D) No P
Correct: A
Rationale: First-degree PR >0.20 prolonged constant every P conducts.

Q7. Third-degree?
A) AV dissociation atria independent
B) One dropped
C) PR prolonged
D) Normal
Correct: A
Rationale: Third-degree complete block atria independent more Ps than QRS no PR pacing needed.

Q8. VT?
