Which ECG description is most consistent with atrial flutter?
Correct answer: B. Sawtooth flutter waves between QRS complexes
- A. Irregularly irregular rhythm without P waves
- B. Sawtooth flutter waves between QRS complexes
- C. Progressively longer PR intervals before a dropped beat
- D. Wide QRS complexes occurring without preceding P waves
Explanation
Atrial flutter produces rapid, regular atrial activity that appears as sawtooth flutter waves, often with a regular or variably conducted ventricular rate. An irregularly irregular rhythm without clear P waves suggests atrial fibrillation, while dropped beats or wide complexes indicate other conduction problems.
