CRAT exam guide
About the Certified Rhythm Analysis Technician (CRAT) exam
The CCI Certified Rhythm Analysis Technician examination is designed for professionals who use specialized monitoring equipment to analyze cardiac rhythms. Use this short diagnostic to identify recognition, troubleshooting, safety, and reporting topics that need more review, then organize further study around the official examination matrix.

CRAT examination matrix
The percentages below are the approximate exam-score weights published by Cardiovascular Credentialing International (CCI). Use them to allocate study time, then adjust for your own weak areas.
9%
Initiating Cardiac Monitoring Services
Begin monitoring with correct patient identification, relevant clinical context, and clear education for the patient or care team.
- Verify patient identification
- Review patient diagnosis, history, and reason for monitoring
- Provide education about the monitoring service, device, placement, safety, and care
9%
Administering Cardiac Tests
Place the monitoring device, obtain a technically usable ECG, relate symptoms to recorded events, and recognize standard recording settings.
- Place the cardiac monitoring device
- Evaluate ECG quality, minimize interference, and troubleshoot problems
- Correlate patient symptoms with events or rhythms
- Recognize standard ECG settings
16%
Analyzing Normal Rhythms
Identify normal ECG components and sinus rhythms by connecting rate, regularity, wave morphology, anatomy, and physiology.
- Identify normal ECG components
- Identify cardiac anatomy and physiology
- Correlate ECG morphology with cardiac anatomy and physiology
- Identify sinus rhythms, rates, regularity, and wave morphology
60%
Analyzing Abnormal Rhythms
The dominant domain tests systematic recognition of atrial, junctional, ventricular, paced, and conduction rhythms while distinguishing true abnormalities from artifact.
- Identify atrial fibrillation, atrial flutter, and other atrial arrhythmias
- Identify junctional and ventricular arrhythmias
- Identify asystole, ventricular tachycardia, and ventricular fibrillation
- Identify paced rhythms and intraventricular conduction delays
- Identify AV conduction defects
- Recognize artifacts
6%
Processing Cardiac Test Findings
Prioritize and compile findings, then complete appropriate reporting and follow-up activities within the technician role.
- Prioritize ECG results
- Compile test findings
- Conduct follow-up activities
How to use this CRAT diagnostic
The 15 questions emphasize abnormal rhythm analysis because it represents 60% of the official matrix, while still sampling monitoring initiation, test administration, normal rhythms, and processing findings. This is a short baseline rather than a pass prediction. For every uncertain answer, identify whether the gap involved rhythm recognition, interval or morphology analysis, artifact, urgency, or communication, then follow with larger mixed rhythm sets.
High-yield CRAT study priorities
Priority 1
Make abnormal rhythm analysis the core
This domain accounts for approximately 60% of the matrix. Use the same sequence for every strip: rate, regularity, P-wave activity, PR relationship, QRS width and morphology, then the relationship between atrial and ventricular activity.
Priority 2
Separate emergencies from routine findings
Practise recognizing ventricular tachycardia, ventricular fibrillation, asystole, and high-risk conduction abnormalities quickly, then pair recognition with the correct priority and escalation within CRAT scope.
Priority 3
Distinguish rhythm from artifact
Review motion, tremor, poor electrode contact, lead reversal, baseline wander, and electrical interference. Confirm signal quality and compare available leads before assigning an abnormal rhythm.
Priority 4
Connect monitoring to communication
Study the whole workflow: verify the patient and indication, place and troubleshoot the device, correlate symptoms, prioritize findings, document accurately, and conduct the required follow-up.
CRAT exam FAQ
How many questions are on the CCI CRAT exam?
CCI currently lists 130 questions: 110 scored questions and 20 unscored questions that are not identified during the examination.
How long is the CRAT exam?
The exam appointment is two hours. CCI allocates 1 hour 50 minutes to answer questions and 10 minutes to the tutorial and post-exam survey.
What is the largest CRAT exam domain?
Analyzing Abnormal Rhythms is the largest domain at approximately 60% of the exam score, followed by Analyzing Normal Rhythms at 16%.
Which CRAT examination matrix does this guide use?
This guide uses the CCI CRAT examination matrix identified by CCI as effective July 1, 2023.
Is the CRAT exam offered year-round?
CCI states that the computer-based CRAT exam is administered year-round at Pearson Professional Centers, subject to test-center availability.
Does this diagnostic predict whether I will pass?
No. A 15-question diagnostic is a low-confidence baseline, not a validated pass prediction. Use it to identify review priorities and confirm current requirements with CCI.
Is MedPorium affiliated with CCI?
No. MedPorium is an independent education platform and is not affiliated with or endorsed by Cardiovascular Credentialing International.
