How to Prevent a Stroke

Find Out if You Have A-Fib

Atrial fibrillation, or a-fib, as doctors call it, is a condition where one of the top chambers beats out of sync with the rest of the heart. This allows blood to pool, which can lead to a clot that travels to the brain. A-fib accounts for about 20 percent of strokes. Few doctors even realize it’s that high, Lee says.

Here’s a quick test to tell if you have an irregular pulse, which can be a sign of atrial fibrillation: Press two fingertips on the opposite wrist and find your pulse. Don’t worry about counting beats; just feel for an even, steady drumbeat. It helps to tap your foot along with each beat.

An irregular beat feels like an extra or missed beat. If you discover this, or if you ever feel like your heart races or flutters for no reason, see a doctor. The effects of a-fib can be controlled with medication or surgery.
