Is it true omega 3 purified fish oil 1000 mg can trigger svt?

UNLIKELY: Millions of people take purified omega 3 fish oil with no adverse effects on heart rhythm. It's not likely that you would have such a reaction while taking them.

Anectdotal: There has been some anecdotal experiences of people getting arrhythmias on fish oils/omega 3's, but the majority of people who take the omega 3's never experience an arrhythmia. If you ever feel you get an abnormal heart rhythm/beat from anything you ingest, you should avoid the substance and tell your dr. Best wishes.
