What's Covered on the CRAT Exam?

The Certified Rhythm Analysis Technician Examination is weighted by six topics. The topics include analyzing rhythms, administering cardiac tests, educating clients, processing cardiac test findings, registering patients, and maintaining cardiac monitoring device support.

Analyzing Rhythms — 68% of Exam Content

Analyzing rhythms is 68% of the exam. You will need a good understanding of the anatomy and physiology of the heart. You should also familiarize yourself with sinus rhythmsatrial rhythms, junctional rhythms, atrial ventricular (AV) conduction and AV conduction disorders. You will also be expected to have knowledge of ventricular rhythms, asystole, artifact, and paced rhythms.

Administering Cardiac Tests — 10% of Exam Content

Administering cardiac tests makes up 10% of the exam. . You will be tested on cardiac equipment application and device management, as well as taking a brief history of patients’ symptoms.

Educating Clients — 8% of Exam Content

Educating clients is 8% of the exam. You will need to be able to give patients information in an appropriate format, ensure accessibility requirements are met, gain informed consent, explain proceedings and empower patients’ to self-manage their devices where appropriate.

Processing Cardiac Test Findings — 6% of Exam Content

Processing cardiac test findings is 6% of the exam. You are expected to know how to triage based on results from ECG tests, collate results, make appropriate referrals and arrange appropriate follow-up.

Registering Patients — 5% of Exam Content

Registering patients is 5% of the exam. You will be expected to know how to validate a provider’s order for an ECG test. Validation includes verification of the patient’s identity, collecting demographic data from the patient, reviewing the patient’s history, and providing the patient with equipment for cardiac monitor devices.

Maintaining Cardiac Monitoring Device Support — of Exam Content

Maintaining cardiac monitoring device support consists of 3% of the exam. You will be expected to verify proper placement of electrodes, cleanse patient equipment, and reduce electrical mechanical interference (EMI) to a minimum.

What’s Next?

Cardiovascular Credentialing International do not provide a course for the CRAT exam. We have compiled a rough guide to terms you will need to know as a basis for your research and revision. The following information contains highlights from our accredited arrhythmia interpretation course.

You can also try our practice quizzes to help you prepare for the CRAT exam’s rhythm analysis section.

Anatomy and Physiology of the Heart (Exam topics covered: Analyzing rhythms)

Pericardium — The heart is contained within a tough double-layered sack for protection, shock absorption and lubrication; there is a small amount of fluid within the pericardium to reduce friction and allow normal movement of the heart.

The Heart Walls — The heart has three layers, or walls: The epicardium, myocardium, and the endocardium.

Cells in the Heart — There are two main types of cell in heart muscle which allow electrical impulses to trigger a strong beat. Sign up for our emails to find out more about the heart cells, and how the heart beat keeps its intrinsic rhythm.

Heart Valves — The heart has valves to ensure that blood only flows the right way through the chambers. Sign up for our emails to learn the names and functions of these structures.

Coronary Arteries — The heart needs its own blood supply to bring oxygen to the myocardium; sign up for our emails to learn more about the coronary arteries, and what happens something goes wrong with your coronary arteries.

Three Main Arteries Sign up for our emails!

Systole and diastole — What do we mean when we talk about systole and diastole? Sign up for our emails to find out more.

Sinoatrial (SA) Node This is the natural pacemaker of the heart. The SA node generates electrical impulses to trigger a heartbeat.

Atrioventricular (AV) Node Sign up for our emails to find out more about the conduction system of the heart.

Purkinje Fibers These fibers spread electrical impulses throughout the myocardium of the ventricles.

What is the Electrocardiogram? (Exam topics covered: Analyzing rhythms, administering cardiac tests, and processing cardiac test findings)

Artifact – Artifact occurs when something external causes electrical interference to appear on the EKG.

Sign up for our emails to learn more about:

Normal Sinus Rhythm – In normal sinus rhythm, the SA node fires between 60 and 100 times per minute.

Sinus Bradycardia – In sinus bradycardia the sinus node triggers a normal heartbeat less than 60 times per minute.

Sinus Tachycardia – In sinus tachycardia the sinus node fires and triggers a normal heartbeat more than 100 times per minute.

Determining Regularity – Measuring complexes on an EKG to determine whether a rhythm is regular or irregular; both caliper and pen and paper methods are used.

P Waves – P waves indicate an electrical impulse arising in the SA node.

QRS Complex – A QRS complex indicates that the ventricles have depolarized.

PR Interval – The interval from the beginning of the P wave to the start of the QRS complex. This interval indicates the depolarization of the atria, which should start at the sinus node.
