Answers to Common Atrial Fibrillation (A-Fib) Questions

Premier Health providers answer frequently asked questions about atrial fibrillation.

Can someone have atrial fibrillation (A Fib) and not know it?

Premier Health’s Dr. Mark Krebs explains if someone can have atrial fibrillation (A Fib) without knowing it.  


The American Heart Association (AHA) has collected a number of patient testimonials about their experience with atrial fibrillation. One patient reports: “I had no symptoms at all. I discovered my AF at a regular check-up. I’m glad we found it early.”

It is not uncommon for someone with atrial fibrillation to be asymptomatic. A 2005 Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) study compared patients with atrial fibrillation who were asymptomatic and those who experienced a variety of symptoms. Of the total 4,060 patients in the study, 12% (481 patients) experienced no symptoms.

Because atrial fibrillation can be asymptomatic, it is especially important for those at higher risk for A Fib to get regular checkups.
