What does atrial fibrillation (AFib) feel like?

ANSWER

Normally, your heart makes a “lub-dub, lub-dub” sound when it beats. It contracts and relaxes to move blood from the upper chambers (called the atria) to the lower ones (the ventricles) and out to your body.

If you have atrial fibrillation, or AFib, you might instead feel a flutter or quiver in your chest when your heart beats. Your heart might beat faster than usual, pound, or race. These are called palpitations.

The feeling often lasts for a few minutes. Sometimes, your heart will skip a beat.
