Important facts about atrial fibrillation
Atrial fibrillation is a common heart rhythm problem and a
common cause of major strokes. It affects 8% of those 65
years and older and about 20% of all strokes are caused by
atrial fibrillation.
Atrial fibrillation is a rhythm problem that can last from a few
minutes, to days or weeks and even years. Atrial fibrillation
can lead to the formation of blood clots in the heart. These
clots can break off and flow to the brain causing stroke.
One sign of atrial fibrillation is palpitations. However, many
people have no symptoms and therefore may remain
undetected whereas diagnosing atrial fibrillation early
followed by adequate treatment can largely reduce the
chance of getting a stroke.
