Hi all!

Having trouble with this rhythm. Not sure whether to call it sinus or afib/aflutter. Here’s my thought process so far:

- R to R looks regular. Rate 140s, then there is a pause, then the rhythm looks like it converts to sinus brady. Since R to R is regular, I’m leaning towards calling it flutter and not afib.

- Someone was calling it afib, is it possible to have a regular rhythm and afib?

- p waves present vs flutter waves? From afar, looks like sinus tach, but looking closely, I can’t tell if those are fibrillatory waves or flutter waves.

What would the full interpretation of this strip be?

Any advice is greatly appreciated! Thank you!
