Introduction
This comprehensive assessment evaluates the competency of
healthcare providers in recognizing, interpreting, and managing
complex cardiac rhythms. It covers foundational electrophysiology,
applied ECG interpretation, pharmacological interventions, device
therapy, and clinical decision-making in acute and critical care
settings. Questions are multiple-choice and scenario-based,
emphasizing real-world application, rapid rhythm identification,
and safe clinical judgment. The examination is designed to reflect
advanced cardiac monitoring and arrhythmia management
,standards and to strengthen readiness for safe, effective clinical
practice.
SECTION ONE: QUESTIONS 1-100
1. On an ECG strip, how many seconds does one small box
represent?
A. 🟢 0.04 seconds
B. 0.08 seconds
C. 0.12 seconds
D. 0.20 seconds
🔴 RATIONALE: Each small box on standard ECG paper represents
0.04 seconds at a paper speed of 25 mm per second. Five small
boxes make one large box, which equals 0.20 seconds.
2. Which structure serves as the primary pacemaker of the heart
under normal conditions?
A. The atrioventricular node
B. 🟢 The sinoatrial node
C. The bundle of His
D. The Purkinje fibres
🔴 RATIONALE: The sinoatrial node, located in the right atrium
near the superior vena cava, normally initiates electrical impulses
,at a rate of 60 to 100 beats per minute, making it the primary
pacemaker of the heart.
3. What is the normal duration of the PR interval?
A. 0.04 to 0.08 seconds
B. 🟢 0.12 to 0.20 seconds
C. 0.36 to 0.44 seconds
D. Less than 0.12 seconds
🔴 RATIONALE: The PR interval represents the time for the
electrical impulse to travel from the atria to the ventricles. A
normal PR interval measures 0.12 to 0.20 seconds.
4. A patient presents with a wide complex tachycardia at a rate of
178 bpm. The QRS duration is 160 ms. Lead aVR shows an
initial R-wave greater than 40 ms. Which criterion is most
consistent with ventricular tachycardia?
A. RBBB morphology with normal axis
B. Onset of tachycardia triggered by a PAC
C. 🟢 AV dissociation with fusion and capture beats
D. Termination with adenosine 6 mg IV
🔴 RATIONALE: AV dissociation with fusion beats (Dressler beats)
and capture beats are pathognomonic for ventricular tachycardia.
These findings confirm that the ventricles are firing independently
of the atria, which is the hallmark of VT.
, 5. What does the QRS complex represent on an ECG?
A. Atrial depolarization
B. 🟢 Ventricular depolarization
C. Ventricular repolarization
D. Atrial repolarization
🔴 RATIONALE: The QRS complex represents ventricular
depolarization, which leads to ventricular contraction. It is
normally less than 0.12 seconds in duration.
6. What does the T wave represent on an ECG?
A. Atrial depolarization
B. Ventricular depolarization
C. 🟢 Ventricular repolarization
D. Atrial repolarization
🔴 RATIONALE: The T wave represents ventricular repolarization,
which is the relaxation phase of the ventricles.
7. Which of the following is the correct sequence of blood flow
through the heart?
A. 🟢 SVC → Right atria → Tricuspid valve → Right ventricle →
Pulmonic valve → Lungs → Left atria → Mitral valve → Left
ventricle → Aortic valve → Aorta → Body
B. SVC → Left atria → Mitral valve → Left ventricle → Aortic valve
