A drug called warfarin is also commonly advised to reduce the risk of having a stroke. Page 1 of 4 Page 2 What is atrial fibrillation ? In atrial fibrillation (AF), the normal controlling 'timer' in the heart does not work. Many random electrical impulses then 'fire off' from the heart muscle in the atria. The atria then 'fibrillate'. This means that the atria only partially contract - but very rapidly (up to 400 beats per minute). Only some of these impulses pass through to the ventricles in a haphazard . . .
