Atrial fibrillation (AFIB)
AFIB is the most common sustained cardiac arrhythmia occurring in 5% of the
population of 65 years and above and in 14% among those older than 85 years. AFIB
leads to a 5-fold higher risk of stroke and is responsible for 20% of all strokes. Many
people have no symptoms from AFIB and therefore remain undiagnosed, whereas
early treatment can reduce the risk of stroke by 68%.
