Introduction
The IBHRE Certified Electrophysiology Specialist-Adult (CEPS-A) exam is designed to
validate the specialized knowledge and clinical competency required for professionals
working in the field of adult cardiac electrophysiology. This comprehensive assessment
evaluates a candidate's proficiency in cardiac anatomy, arrhythmia mechanisms,
diagnostic mapping, and therapeutic intervention strategies. The exam comprises a mix of
,foundational multiple-choice questions and complex scenario-based assessments that
mirror real-world clinical challenges. By emphasizing critical thinking and evidence-based
decision-making, this exam ensures that certified specialists are equipped to provide high-
quality, safe, and effective patient care during intricate EP procedures and device
implantations.
SECTION ONE: QUESTIONS 1–100
1. During a diagnostic EP study, which of the following catheters is traditionally placed
in the most anterior and superior position within the right atrium?
A. His bundle catheter
B. Coronary sinus catheter
C. High right atrium catheter
D. Right ventricular apex catheter
🟢 C. High right atrium catheter
🔴 Explanation: The High Right Atrium (HRA) catheter is typically positioned at the
junction of the superior vena cava and the right atrium, near the sinus node, making it the
most superior and anteriorly placed catheter in a standard setup.
, 2. A patient presents with a narrow complex tachycardia. During the study, the V-A
interval is measured at 60 ms. Which of the following is the most likely diagnosis?
A. Orthodromic AVRT
B. Typical AVNRT
C. Permanent Form of Junctional Reciprocating Tachycardia
D. Atrial Tachycardia
🟢 B. Typical AVNRT
🔴 Explanation: Typical (slow-fast) AVNRT is characterized by a very short V-A interval,
usually less than 70 ms, because the atrial activation occurs nearly simultaneously with
ventricular activation.
3. Which of the following best describes the "Wolf-Parkinson-White" pattern on a 12-
lead ECG?
A. Prolonged PR interval and narrow QRS
B. Short PR interval and delta wave
C. Short PR interval and notched P wave
D. Prolonged QT interval and U waves
🟢 B. Short PR interval and delta wave
, 🔴 Explanation: WPW syndrome is characterized by pre-excitation via an accessory
pathway, which bypasses the AV node delay, resulting in a short PR interval and a slurred
upstroke of the QRS complex (delta wave).
4. Which pharmacological agent is most appropriate for terminating a suspected
adenosine-sensitive atrial tachycardia?
A. Adenosine
B. Verapamil
C. Digoxin
D. Lidocaine
🟢 A. Adenosine
🔴 Explanation: Adenosine is the first-line agent for both the diagnosis and termination of
narrow complex tachycardias that involve the AV node or specific triggered focal atrial
tachycardias.
5. In the context of fluoroscopy, the ALARA principle stands for:
A. As Low As Reasonably Achievable
B. Always Lower All Radiation Amounts
