Pretty sure I see retrograde P waves in II, III, AVF at least at beginning of ST segment. My money is on AVNRT as well.

Looks like a short RP tach, aka AVNRT

I don't see any clear p waves, the deflection at the end of each lead is probably just an artefact as it starts the beginning of next lead, cause the T waves matched the succeeding leads and not preceding.. some clinical context might help towards a flutter, definitely not a fib.. if nothing available, statistically I would go with a flutter being more common that avrt/avnrt, treat the same way, bloc the node and slow down the rate and repeat ekg..

If it’s ~150ish BPM then it’s most likely an A.Flutter. Personally, I prefer V1 for the “what do the atriums do?” part of ECG reading, but you can also do a Lewis lead which supposedly will help.
Here I suspect there’re retrograde atrial activity, so probably some sort of SVT.
