Which ECG finding is most consistent with atrial fibrillation?
Correct answer: B. Irregularly irregular rhythm with no distinct P waves
- A. Regular rhythm with a P wave before every QRS
- B. Irregularly irregular rhythm with no distinct P waves
- C. Wide QRS complexes occurring at a regular slow rate
- D. Saw-tooth flutter waves with a regular ventricular rhythm
Explanation
Atrial fibrillation produces chaotic atrial activity, absent distinct P waves and an irregularly irregular ventricular rhythm. A regular rhythm with clear P waves suggests sinus rhythm, while saw-tooth waves suggest atrial flutter.
