fib·ril·la·tion

 (fĭb′rə-lā′shən, fī′brə-)
n.
1. The forming of fibers.
2.
a. Fine, rapid twitching of individual muscle fibers with little or no movement of the muscle as a whole.
b. Rapid uncoordinated twitching movements that replace the normal rhythmic contraction of the heart and may cause a lack of circulation and pulse.

fibrillation

(ˌfaɪbrɪˈleɪʃən; ˌfɪb-)
n
1. (Physiology) a local and uncontrollable twitching of muscle fibres, esp of the heart, not affecting the entire muscle. Atrial fibrillation results in rapid and irregular heart and pulse rate. In ventricular fibrillation, the heart stops beating
2. (Pathology) irregular twitchings of the muscular wall of the heart, often interfering with the normal rhythmic contractions

fi•bril•la•tion

(ˌfaɪ brəˈleɪ ʃən, or, esp. for 2, ˌfɪb rə-)

n.
1.
a. uncontrolled twitching or quivering of muscular fibrils.
b. chaotic contractions across the atrium of the heart, causing fast and irregular ventricular activity; arrhythmia.
2. the formation of fibrils.

fib·ril·la·tion

(fĭb′rə-lā′shən)
A rapid twitching of muscle fibers, as of the heart, caused by the abnormal discharge of electrical nerve impulses.

fibrillation

the uncontrolled twitching of the muscular fibrils, especially of the cardiac muscles.
