Is atrial fibrillation regular?

Atrial fibrillation is not regular. It arises from chaotic electrical activity in the atria, so there are no coordinated P waves and the ventricular response is conducted in an unpredictable way. This makes the intervals between beats (the R-R intervals) vary from beat to beat, giving an irregular rhythm described as irregularly irregular. Because of that, the simple statement that AF is regular is false, and the best answer is No.
