1. Which of the following is the correct rate for sinus
tachycardia?
o A) 60-100 bpm
o B) 100-150 bpm
o C) 150-200 bpm
o D) 200-250 bpm
Rationale: Sinus tachycardia is defined as a heart rate over 100
bpm, typically between 100-150 bpm.
2. In atrial fibrillation, which of the following is true about the P
waves?
o A) They are absent
o B) They are regular and uniform
o C) They are absent or replaced by fibrillatory waves
o D) They are normal but have a short PR interval
Rationale: Atrial fibrillation is characterized by the absence of P
waves and the presence of fibrillatory waves.
3. What is the primary characteristic of a first-degree AV block?
o A) Dropped QRS complexes
o B) Prolonged PR interval
o C) Shortened PR interval
o D) Irregular R-R intervals
Rationale: A first-degree AV block is identified by a PR interval
longer than 0.20 seconds.
4. Which rhythm is identified by the absence of all electrical
activity on the ECG?
, o A) Ventricular fibrillation
o B) Sinus arrest
o C) Atrial standstill
o D) Asystole
Rationale: Asystole is recognized by the absence of any electrical
activity on the ECG, indicating no cardiac function.
5. What is the defining feature of a premature ventricular
contraction (PVC)?
o A) Prolonged PR interval
o B) P wave preceding the QRS complex
o C) Wide and bizarre QRS complex
o D) Narrow QRS complex
Rationale: PVCs are characterized by wide and bizarre QRS
complexes that occur earlier than expected.
6. In which condition is the QRS complex typically less than 0.12
seconds?
o A) Sinus rhythm
o B) Bundle branch block
o C) Ventricular tachycardia
o D) Ventricular fibrillation
Rationale: In a normal sinus rhythm, the QRS complex duration is
less than 0.12 seconds.
7. Which arrhythmia is often treated with synchronized
cardioversion?
o A) Sinus bradycardia
o B) Ventricular fibrillation
o C) Atrial flutter
o D) Junctional rhythm
, Rationale: Synchronized cardioversion is commonly used to treat
atrial flutter.
8. Which rhythm is characterized by a rate of 150-250 bpm with
regular R-R intervals and P waves often buried in the
preceding T wave?
o A) Sinus tachycardia
o B) Supraventricular tachycardia (SVT)
o C) Atrial fibrillation
o D) Ventricular tachycardia
Rationale: SVT typically has a rapid rate with regular intervals
and P waves that may be hidden in the T waves due to the fast rate.
9. What is the most appropriate initial treatment for ventricular
fibrillation?
o A) Atropine
o B) Defibrillation
o C) Epinephrine
o D) Amiodarone
Rationale: The primary treatment for ventricular fibrillation is
immediate defibrillation to restore a normal rhythm.
10. Which of the following rhythms is characterized by
progressively lengthening PR intervals until a QRS complex is
dropped?
o A) Second-degree AV block, Mobitz type I (Wenckebach)
o B) Second-degree AV block, Mobitz type II
o C) Third-degree AV block
o D) First-degree AV block
Rationale: Mobitz type I block features progressively lengthening
PR intervals followed by a dropped QRS complex.
11. What is a key characteristic of atrial flutter on an ECG?
