What are the inclusive characteristics of atrial fibrillation?

Atrial Fibrillation. Atrial fibrillation is a condition where the atria of the heart no longer have an organized electrical activity and hence do no longer fulfill their pumping function properly. The typical ECG finding is for an irregularly irregular rhythm with absence of p-waves.
Irregular fast. Instead of the top chambers (atria) of heart beating 70-80 times a minute, they fibrillate or quiver at 1000 (red) times a minute, not all impulses are conducted down because of the av node a gate keeper. This can be seen on an ekg the p waves are replaced with fibrillation waves. Blood clots can form inside the heart when the atria are fibrillating, these can travel to the brain causing strokes.
