What are the mechanisms for skipped heartbeats after COVID infection?

In which ways can COVID cause pvc's / svt / PAC's, i.e. ectopic heartbeats from electrical disturbances in the heart? And what would the treatment be?

So far I came up with:
- Electrolyte imbalances due to alteration of organ function
- Histamine intolerance
- MCAS
- Food sensitivities (i.e. oxalates, histamine, etc) due to alteration of the microbiome
- Gut and stomach problems such as bloating, gas, etc which irritates the vagus nerve due to alteration of the gut microbiome
- Malabsorption
- SIBO
- Dysautonomia
- Myocarditis
- Viral persistence ?
- Micro blotclots?

Anything else? And are all these things a life sentence with managing symptoms? Or are somethings actually curable? Anyone who found the root cause and had success treating it?

I want these fuckers gone. My heart is supposedly healthy (echo / holter / ECG) and my microbiome in a poor state (Biomesight stool test results), but more I don't know. I have no other cardiac symptoms, only daily skipped heartbeats. I am trying to figure out if I should pursue more medical testing or simply learn how to accept it isn't getting better. Thanks.
