Fibrillation

Fibrillation

Dr. Kennedy
As relates to the heart, fibrillation is an uncoordinated twitching of the heart muscle fibers. The difference between fibrillation and flutter is that fibrillation is not well organized while flutter is well organized. For example, atrial flutter is regular, organized but over-rapid contraction of the atrium of the heart. By contrast in atrial fibrillation, the atrium quivers incoordinately and ineffectually.
