IV abx - arrhythmia

I had my last IV Doxy today (yay! I hope it will have killed that mean yersiniosis). But I've been having arrhythmia for 4or 5 days now: palpitations, feeling of skipping beats, rapid hb.

The only thing I have changed is going to the physiotherapist for revalidation (lumbar fracture), so probably releasing a lot of toxins. I have a picc line (no fever, vein doesn't hurt). And I'm taking Banderol (never had this specific problem with Banderol).

Anyone have experience with arrhythmia during IV Doxy? I didn't have this while taking oral Doxy before.

I know that if it'll continue I will need to go and see the dr, cause it's pretty intense.
Just wanted to inform about this... It can be reassuring if others had the same issue.
