Atrial flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart (the atria) beat too fast. When the top of your heart (atria) beats faster than the bottom (ventricles), it complicates your heart rhythm.
The crude incidence rate of all AF-associated stroke was 60/100,000 person-years. Prior stroke was almost twice as common in AF compared to non-AF groups . The frequency of AF progressively increased across ischaemic stroke patients stratified by increasing stroke severity . The 90-day trajectory of recovery of AF-associated stroke was identical to that of non-AF stroke, but Rankin scores in AF stroke remained higher at 7, 28 and 90 days (p < 0.001 for all).
