INTRODUCTION
The Certified Cardiographic Technician (CCT) exam evaluates the candidate’s competency
in performing cardiovascular diagnostic procedures and interpreting cardiac rhythms. It
assesses foundational knowledge of cardiac anatomy, electrophysiology, and advanced
ECG analysis, alongside practical skills such as patient preparation, equipment handling,
and stress testing. The exam includes multiple-choice and scenario-based questions
designed to measure clinical judgment, technical accuracy, and adherence to safety and
ethical standards. Emphasis is placed on real-world applications, ensuring candidates are
prepared to function effectively in clinical environments while maintaining professionalism
and patient-centered care.
SECTION 1: QUESTIONS 1–35
,1. Which structure initiates the electrical impulse in the heart?
A. AV node
🔴 B. SA node
C. Bundle of His
D. Purkinje fibers
🔵 Explanation: The sinoatrial (SA) node is the heart’s natural pacemaker, initiating
electrical impulses.
2. What does the P wave represent on an ECG?
A. Ventricular depolarization
🔴 B. Atrial depolarization
C. Ventricular repolarization
D. Atrial repolarization
🔵 Explanation: The P wave reflects atrial depolarization as impulses spread across
the atria.
3. A normal adult resting heart rate is:
A. 40–60 bpm
🔴 B. 60–100 bpm
C. 100–120 bpm
D. 120–160 bpm
, 🔵 Explanation: The standard normal resting heart rate range is 60–100 beats per
minute.
4. Which electrolyte imbalance most commonly causes peaked T waves?
A. Hypokalemia
🔴 B. Hyperkalemia
C. Hypocalcemia
D. Hypernatremia
🔵 Explanation: Elevated potassium levels (hyperkalemia) produce tall, peaked T
waves.
5. What is the primary function of the AV node?
A. Initiate impulse
🔴 B. Delay impulse
C. Conduct impulse rapidly
D. Repolarize ventricles
🔵 Explanation: The AV node delays conduction to allow ventricular filling.
6. Which lead provides a view of the heart’s inferior wall?
A. I
