This requires a deep understanding of the various components of an EKG, waveform characteristics, and the ability to identify abnormalities and interpret their clinical significance for patient care.

Additionally, EKG acquisition, which involves properly placing electrodes and obtaining accurate readings, can also be challenging.

• Identifying atrial fibrillation
  
  
• Recognizing ventricular tachycardia
  
  
• Calculating heart rate from rhythm strips
  
  
• Understanding P waves, QRS complex, T waves
  
  
• Differentiating normal sinus rhythm vs arrhythmias

What is the pass rate for the EKG certification test?

NHA scores the CET on a scale of 200 to 500, and you need a scaled score of 390 to pass. NHA reports that 69.66% of the 19,241 CET exams administered in 2024 were passed; the report does not separate first attempts from retakes.
