I was comfortable with some EKG terminology but less confident when I had to recognize and interpret different rhythms quickly. My CET preparation became more useful once I started reviewing waveform patterns, electrode placement, and cardiac rhythms together instead of studying each topic separately.

Frequently Asked Questions
What is the CET exam?
The Certified EKG Technician exam is a test to assess whether candidates have the knowledge and skills to perform electrocardiograms safely and accurately. It covers heart monitoring, patient care, and reading EKG results, allowing technicians to work in healthcare settings such as hospitals and clinics.
Who administers the CET exam?
The National Healthcareer Association (NHA) runs the CET exam. They manage the application process, testing locations, and certification decisions. Testing is done either at physical PSI centers or remotely via online proctoring.
What are the eligibility requirements to take the CET exam?
You must have a high school diploma or equivalent and complete an approved EKG training program. After passing the exam, you are required to complete 10 live EKG procedures on patients within 180 days to receive full certification.
How many questions are on the CET exam?
The exam consists of 100 multiple-choice questions developed to assess your knowledge in three areas: safety and patient care, EKG acquisition, and EKG analysis.
What topics are covered in the safety and patient care section?
This section includes the proper handling of patient information, infection control steps, ensuring patient safety during procedures, and how to recognize signs of distress or complications requiring urgent attention.
What do I need to know about EKG acquisition?
You should understand how to prepare the equipment, clean and prepare the skin for electrodes, place leads correctly, troubleshoot common problems like artifact interference, and assist with stress testing when needed.
What skills are tested in EKG analysis and interpretation?
This section assesses your ability to calculate heart rate and rhythm, identify normal and abnormal waveforms, measure electrocardiogram intervals, and detect arrhythmias or other irregularities.
How do I apply for the CET exam?
First, create an account on the NHA website. Then submit your application online, upload proof of training if required, and pay the exam fee.
What study materials are available for the CET exam?
NHA offers official study guides, Prephow CET practice questions, quizzes, and video tutorials. There are also free online practice tests and books focused on EKG technician skills to help prepare you.
Do I need clinical experience before the exam?
Hands-on clinical experience is part of your training program, but the requirement to perform 10 live EKGs on patients occurs after you pass the exam and before full certification.
What are common EKG reading challenges on the CET exam?
You will be expected to identify arrhythmias such as atrial fibrillation and ventricular tachycardia, measure interval lengths like PR and QRS, and recognize signs of heart damage.
How is EKG artifact identified and corrected?
Artifacts show up as irregular waves caused by patient movement, loose electrodes, or electrical interference. Fix these by repositioning leads, ensuring cables are secure, or reducing patient motion during recording.
