INTRODUCTION
The Certified Rhythm Analysis Technician (CRAT) exam evaluates a candidate’s ability to
accurately interpret cardiac rhythms and apply clinical knowledge in patient monitoring
environments. The assessment focuses on ECG analysis, arrhythmia identification, and
appropriate clinical responses in both routine and emergency scenarios. Candidates must
demonstrate proficiency in cardiac electrophysiology, equipment use, and patient safety
protocols. The exam consists of multiple-choice and scenario-based questions designed to
assess critical thinking, professional judgment, and adherence to healthcare standards.
Emphasis is placed on real-world application, ensuring readiness for clinical practice in
telemetry and cardiac monitoring settings.
,SECTION 1: QUESTIONS 1–35
1. Which structure initiates the normal cardiac impulse?
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 is the normal resting heart rate range for adults?
A. 40–60 bpm
🔴 B. 60–100 bpm
C. 100–120 bpm
D. 120–160 bpm
🔵 Explanation: Normal adult resting heart rate is 60–100 beats per minute.
, 3. Which ECG component represents ventricular depolarization?
A. P wave
B. T wave
🔴 C. QRS complex
D. PR interval
🔵 Explanation: The QRS complex reflects ventricular depolarization.
4. A prolonged PR interval indicates:
A. Ventricular hypertrophy
🔴 B. First-degree AV block
C. Atrial fibrillation
D. Sinus tachycardia
🔵 Explanation: A PR interval >0.20 seconds indicates delayed conduction through
the AV node.
5. What rhythm is characterized by irregularly irregular R-R intervals?
A. Sinus rhythm
B. Atrial flutter
🔴 C. Atrial fibrillation
