EKGQuestion 79 of 100
An EKG shows an irregularly irregular rhythm with no clearly identifiable P waves. This is most consistent with:
a.Normal sinus rhythm
b.Sinus bradycardia
c.Atrial fibrillation
d.First-degree heart block
Explanation
Atrial fibrillation appears as an irregularly irregular rhythm with no discernible P waves, replaced by a chaotic, wavy baseline. It results from disorganized electrical activity in the atria. The technician should document the finding and notify the nurse, especially if the rate is rapid or the patient is symptomatic.
