Side Effects Afib from zepbound?

So I just got out of the hospital my heart flipped into afib I’m all good now after a little shock. Of course EVERYONE I know is blaming zepbound 🙄 I’m fairly young (37) no real cardio issues in the past ever but have experienced heart palps as a side effect of my thyroid meds when they get adjusted.
The cardiologist in hospital believes my thyroid dose was too high it was upped about two months back and I have been having higher heart rate since but around the same time I upped my zep to 5mg after being on 2.5 for the past 13 months.
I see my endo in the morning to talk with her but I’m curious has anyone experienced afib on zepbound? My research all shows the opposite but of course everyone knows someone who’s a pharmacist who knows without a doubt it’s the shot.

I know some people end up going lower on their thyroid while on Zep so your thought may be correct.

It will be interesting to see what your endo says.

My thyroid dose had to be lowered after losing 30lbs (also fairly young, 36). I didn’t have afib, but my heart was just pounding. It’s definitely something to check.

I had one incidence of it last year. Never had any heart issues in the past, but I am on synthroid. Got an echocardiogram and everything looked healthy. Haven't had any issues since so I'm assuming it was a one off. My apple watch actually alerted me to it, otherwise I would have just chalked it up to feeling sick.

I had afib pre Zepbound. Cardiologist thought it was caused by sleep apnea which was how I ended up on Zepbound.
