  1. Mar 8, 2024 · Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm. An irregular heart rhythm is called an arrhythmia. AFib can lead to blood clots in the heart. The condition also increases the risk of stroke, heart failure and other heart-related complications.

    • Atrial fibrillation is a condition that disrupts your heartbeat. A glitch in the heart’s electrical system makes its upper chambers (the atria) beat so fast they quiver, or fibrillate.
    • Usually the atria and ventricles work together so the heart pumps blood in steady rhythm. But in AFib, they don't. The irregular beats can cause a fast, fluttering heart rate -- 100-175 beats per minute -- instead of the normal 60-100 beats per minute.
    • For many people, AFib symptoms aren't obvious . But when there are, they'll often include: An uneven pulse. A racing or pounding heart. A feeling that your heart is fluttering.
    • When your heart is in AFib, your blood doesn't move well throughout your body. You may feel: Dizzy or faint. Breathless. Weak and fatigued.
