@domiha what is your CHADS score?

I have had afib for anywhere from 45 minutes to 7 hours, once a year on average, since 2015. I declined blood thinners despite pressure from my first cardiologist. He told me a few years later that I was right and they were overmedicating people (one CHADS at that time removed female gender as a point for anticoagulation).Do you have high blood pressure, diabetes, other factors? https://www.mdcalc.com/calc/801/cha2ds2-vasc-score-atrial-fibrillation-stroke-risk If you had a TUA that is a signficant risk factor.

I saw another cardiologist in the hospital who said "Just go home and forget it happened." So there is clearly some disagreement on this issue. I do understand that doctors have less liability if they prescribe then if they don't.

I will say that though a month long monitor picked up some tachcardia and bradycardia, it did not pick up afib at all. So that is a difference between you and me. How long was your afib episode on the monitor? Was there only one episode and it was short?

Some people do anticoagulant short term after an episode. I am trying to find a doctor who will prescribe that. One hospital did an echocardiogram to check for clots after an episode.

Can you ascertain how often you are having afib? Do you have a smartwatch or Kardia?

I am not questioning your doctor's advice and we all need to rely on an MD. I just get second opinions when I have uncertainty.
