The article references a meta-analysis, which is hardly a smoking gun.

The analysis suggests variation between afib occurrence/risk and the brand or omega-3 supplement or dose.

Additional points from the article:

* despite finding a link between afib and omega-3 supplementation, the meta-analysis didn’t find increased heart or stroke risk

* although the analysis linked a prescription-strength omega-3 supplement with higher afib risk, the analysis indicated that omega-3 appeared to reduce heart attack and stroke risk

Existing evidence and analysis find that omega-3 can impact various medical conditions and health factors.

I think that, as with any medication, one should consult their doctor and weigh the cost-benefit / risk-reward of taking omega-3 supplements/prescriptions.
