Meanings
plural fibrillations
- countableuncountableThe rapid, irregular, and unsynchronized contraction of the muscle fibers of the heart.
The most common type of irregular heartbeat is atrial fibrillation or AFib. It is estimated that between three and six million people in the United States have AFib.
2024 February 13, “Understanding Your Heart Rate”, in Emory Healthcare1 more example
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.
