fibrillation

/ˌfɪbɹɪˈleɪʃən/

noun fibrillations

countable, uncountable The rapid, irregular, and unsynchronized contraction of the muscle fibers of the heart. Though occasionally a “flatliner” can be revived with a defib, it is most commonly used to change the uncoordinated contractions of the heart (fibrillation) into a normal sinus rhythm—that is, to defibrillate the heart.
