Time Allowed: 4 Hours
Total Questions: Approximately 200 (This section contains Questions 1–30)
Instructions to Candidates:
Read each question carefully and select the single best answer. Each question
carries equal marks. There is no negative marking. Clinical judgment,
interpretation of electrophysiologic data, and applied knowledge of cardiac
rhythm management are essential. Calculators may be used for interval and
rate calculations. Ensure all answers are marked clearly. Do not leave any
question unanswered.
Disclaimer:
This examination is an original simulation designed for educational purposes. It
is inspired by the structure and competency domains of the official IBHRE
CEPS-A examination but does not replicate actual exam content.
Core Competency Domains:
• Cardiac Electrophysiology Principles
• Device Therapy (Pacemakers, ICDs, CRT)
• Arrhythmia Mechanisms and Diagnosis
, • Intracardiac Mapping and Ablation Techniques
• ECG and Intracardiac Signal Interpretation
• Pharmacology of Antiarrhythmic Drugs
• Patient Management and Safety
This certification assessment evaluates advanced clinical knowledge and
applied decision-making in adult cardiac electrophysiology. Candidates are
expected to demonstrate expertise in arrhythmia mechanisms, device therapy,
intracardiac mapping, and procedural interpretation. Mastery of electrogram
analysis, pacing maneuvers, and ablation strategies is essential for success.
Q1. A patient undergoing EP study demonstrates a narrow complex
tachycardia with a VA interval of 40 ms. What is the most likely
mechanism?
A. Orthodromic AVRT
B. Atypical AVNRT
C. Typical AVNRT
D. Atrial tachycardia
Correct Answer: C. Typical AVNRT
Explanation: A short VA interval (<70 ms) strongly suggests typical
AVNRT. Orthodromic AVRT typically has longer VA intervals. Atrial
tachycardia would show longer VA with atrial activation preceding ventricular.
Atypical AVNRT has longer VA intervals.
Q2. During ventricular pacing, VA dissociation is observed. What does this
indicate?
,A. Presence of accessory pathway
B. AV node involvement
C. Absence of retrograde conduction
D. Dual AV nodal physiology
Correct Answer: C. Absence of retrograde conduction
Explanation: VA dissociation means atria and ventricles are not linked
retrogradely, indicating no retrograde conduction. Accessory pathways or AV
node involvement would produce VA conduction.
Q3. Which antiarrhythmic drug primarily prolongs phase 3
repolarization?
A. Lidocaine
B. Amiodarone
C. Flecainide
D. Verapamil
Correct Answer: B. Amiodarone
Explanation: Amiodarone is a Class III drug that prolongs repolarization
(phase 3). Lidocaine (Class IB) shortens repolarization, flecainide (Class IC)
affects phase 0, and verapamil (Class IV) affects calcium channels.
Q4. A delta wave on ECG indicates:
A. AV nodal delay
B. Pre-excitation via accessory pathway
, C. Bundle branch block
D. Atrial enlargement
Correct Answer: B. Pre-excitation via accessory pathway
Explanation: Delta waves represent early ventricular activation via an
accessory pathway. AV nodal delay would prolong PR, not create delta waves.
Q5. What is the hallmark of typical atrial flutter?
A. Irregularly irregular rhythm
B. Sawtooth flutter waves
C. Narrow QRS with delta wave
D. Prolonged PR interval
Correct Answer: B. Sawtooth flutter waves
Explanation: Classic atrial flutter shows sawtooth waves, especially in
inferior leads. Irregular rhythm suggests AF.
Q6. Which structure is targeted in slow pathway ablation for AVNRT?
A. His bundle
B. Coronary sinus
C. Posterior septal right atrium
D. Left atrial appendage
Correct Answer: C. Posterior septal right atrium
Explanation: Slow pathway lies in posterior septal RA near coronary sinus.
His bundle ablation risks AV block.
