Frequently Asked Questions

What is the NHA Certified EKG Technician (CET) certification?

The CET is a credential from the National Healthcareer Association that shows you can perform EKG procedures safely and accurately. It's popular with hospitals, cardiology offices, and clinics hiring monitor and EKG techs. Passing it proves you know the basics of cardiac anatomy, lead placement, and rhythm basics.

How many questions are on the EKG technician certification?

The NHA CET has 110 multiple-choice questions, and 100 of them are scored. The other 10 are pretest items used to evaluate future questions, and you won't know which ones they are. You get 2 hours and 10 minutes to finish, which is plenty of time if you pace yourself.

What score do I need to pass the CET?

NHA reports scores on a scaled range of 200 to 500, and you need 390 to pass. That's not a simple percentage, because the scale accounts for how hard your particular question set was. Aim to be comfortably above 80% on practice questions before you schedule.

What topics does the EKG practice questions section cover?

The content breaks into safety, compliance, and coordinated patient care, EKG acquisition, and EKG analysis and interpretation. Expect questions on cardiac anatomy and electrophysiology, lead placement, rhythm recognition, artifact troubleshooting, and patient preparation. Our cardiac monitor technician questions hit all of those areas.

How much does the NHA EKG technician exam cost?

The CET fee is about $117 when you register through NHA. Employers and schools sometimes cover it, so ask before paying out of pocket. Fees can change, so double-check on the NHA site when you register.

What is the hardest part of the EKG technician certification?

Most people say rhythm recognition. Telling a sinus rhythm from atrial flutter, or a first-degree block from a second-degree block, takes repetition. Practice measuring PR intervals and QRS width, and work through lots of strips until the patterns feel automatic.

How should I study with an EKG technician practice test?

Start with a baseline run of questions to find your weak spots. Then focus on lead placement landmarks, the normal conduction pathway, and the common rhythms and artifacts. Review every explanation, even for questions you got right, since wrong-answer choices often teach as much as the right one. Most people do well with two to four weeks of steady practice.

Can I retake the CET if I don't pass?

Yes. NHA lets you retest, though there's a waiting period between attempts and you'll pay the fee again. Policies can change, so confirm the current retake rules on the NHA website. Use the gap to drill the sections where you scored lowest.
