One of the most common misconceptions I hear from patients: mild AFib means low risk.
It doesn't.
Patients with atrial fibrillation, even those with occasional or barely noticeable episodes, still have a 5x higher risk of stroke than those without AFib.
The irregular rhythm allows blood to pool in the heart and form clots. AFib that's caught early is AFib that's treated early.
