It is atrial flutter with 2:1 conduction. There are clear flutter waves in lead II across the bottom. In V1, there are upright waves that appear to be P-waves but are not: they are atrial waves and it is typical for atrial flutter waves to be upright in V1, whereas sinus P-waves are biphasic in V1.

In the first section of the ECG we see coarse fibrillation waves and QRS complexes with very different RR intervals, which is why this is atrial fibrillation. It is not atrial flutter because the fibrillation waves are of different size and polarity (depending on the lead) and the intervals between the atrial actions are irregular.

The patient’s history is notable for paroxysmal atrial fibrillation, which raises clinical suspicion for atrial flutter, since these two entities frequently coexist on a spectrum.
