But if you have atrial fibrillation, or AFib, the heart doesn’t always beat or keep pace the way it should. Many people with AFib say they can feel their heart racing, fluttering or skipping beats.
AFib is the most common heart rhythm disorder (arrhythmia). A major concern with AFib is that it also makes blood clots in the heart that can travel and cause strokes or block flow to other critical organs.
In fact, people with this condition are 5 times more likely to have a stroke than people without the condition. It can also lead to heart failure. But finding and treating AFib early on can help you avoid these problems.
