Passed CET on first try — here's how I learned to read rhythms consistently

Got my CET results back last week and I passed with a 79%. I'd been nervous about this one because I came into the prep process with maybe 60% of the rhythm recognition knowledge I needed — I could identify the common ones reliably but some of the less common arrhythmias I was genuinely shaky on. Eight weeks of focused prep turned that around.

The rhythm strip interpretation questions are the core of this exam and there's no shortcut — you have to see hundreds of strips before the patterns become automatic. I went through about 400 practice strips in total, which sounds like a lot but it's really only about 50 a day over 8 weeks. The key for me was identifying strips by rate first, then regularity, then P-wave morphology. Having a consistent system meant I wasn't starting from scratch on each one.

Beyond rhythm interpretation the exam covers anatomy, equipment operation, and patient preparation. I'd estimate roughly 40% rhythm strips, 25% anatomy and physiology, 20% equipment and technical procedures, and 15% patient care and communication. The anatomy section was heavier on cardiac anatomy specifically than I expected — not just the conduction system but the actual structural anatomy.

Exam day the facility was cold and I wish I'd worn layers. The exam is 110 questions and I finished in about 90 minutes. There were 3-4 rhythm strips I genuinely wasn't sure about; on one of them I changed my answer and I'm pretty sure I changed it to the wrong one. Overall the difficulty level felt fair and representative of the prep materials I used.
