The state of being reduced to fibers.
involuntary brief twitch of a muscle; visible under the skin & not associated with movement of the affected muscle
Rapid, uncoordinated contractions of individual heart muscle fibers.
Unco-ordinated contractions of the heart muscle occurring when the individual muscle fibres take up independent irregular contractions. With ventricular fibrillation the heart effectively stops (cardiac arrest).
Quivering of heart muscle fibers.
uncoordinated tremors or twitching of cardiac muscle resulting in an irregular heartbeat and pulse.
A rapid and chaotic beating of the many individual muscle fibres of the heart, which is consequently unable to maintain effective synchronous contraction. The affected part of the heart then ceases to pump blood.
Freeing of the fibrils from within the fibre during the beating/refining process.
Rapid, tremulous, ineffectual contractions of the ventricles; a lethal dysrhythmia.
When something quivers uncontrollably. See 'ventricular fibrillation' and 'atrial fibrillation'
Chaotic, disorganized beating of the myocardium in which each myofibril contracts and relaxes independently, producing rapid, tremulous, and ineffectual contractions. Fibrillation may occur in both the atria and the ventricles.
Uncoordinated contractions of individual muscle cells that impair or prevent normal function.
muscular twitching involving individual muscle fibers acting without coordination
A condition in which a very rapid, unsychronized, beating of different parts of the heart occur. Essentially the parts quiver, rather than beat together. The most serios fibrillation is "V-Fib" (Ventricular Fibrilation), where the main pumping chambers of the heart quiver, rather than pump blood. The fix for this is electrical defibrillation, using a device called a defibrillator (the paddles you see on TV).
A serious medical condition; basically the heart muscle spasms out of control
the act of breaking up the surface of cellulose fibres during the beating process.
Rapid, randomized atrial or ventricular contractions causing an irregular, often rapid ventricular heart rate.
Totally disorganized electrical activity within the heart which produces an ineffective pumping of the heart.
When the heart muscle fibers contract individually and quickly disabling the heart from pumping effectively.
When a heart chamber "quivers" due to an abnormally fast rhythm and can no longer pump blood well. Fibrillation of the atrium is called atrial fibrillation (AF); in the ventricle it is called ventricular fibrillation (VF). Ventricular fibrillation usually leads to death. View illustration
Quivering or uncoordinated muscular contraction.
Rapid and irregular contraction of heart muscle, causing irregular heartbeat.
Fast uncontrolled heart beat
A rapid, uncoordinated contraction of individual heart muscle fibers. The heart chamber involved can't contract at once and pumps blood ineffectively.
Rapid, inefficient contraction of muscle fibers of the heart caused by disruption of nerve impulses.
rapid contractions of the heart muscles.
A structural change occurring in the walls of chemical pulp fibres during beating
Quivering, twitching contraction of muscle fibres, acting singly or in isolated groups instead of together.
Rapid, uncoordinated contraction (squeezing) of the heart muscle.
See 'Ventricular Fibrillation' and ' Artrial Fibrillation'.
A rapid, uncoordinated series of contractions of some part of the heart muscle causing irregular heartbeats. Atrial fibrillation is the rapid, ineffective beating of the upper part of the heart. Ventricular fibrillation is the lethal rapid, ineffective beating of the lower part of the heart.
In matters of the heart (cardiology), fibrillation is incoordinate twitching of the heart muscle fibers. See the entire definition of Fibrillation
An erratic, chaotic quivering of the myocardium during which the heart cannot effectively pump blood. Fibrillation of the atrium is called atrial fibrillation (AF); in the ventricle it is called ventricular fibrillation (VF). Ventricular fibrillation is typically fatal if not corrected within several minutes.

A type of cardiac arrhythmia characterized by rapid, unsynchronized quivering of atria or ventricles. Atrial fibrillation may be asymptomatic, but ventricular fibrillation is typically fatal if not corrected within minutes.
uncontrolled rapid contraction of the fibers in the heart that occurs in the atrial, or upper, chambers (atrial fibrillation) and in the ventricular, or lower, chambers (ventricular fibrillation)
A rapid and irregular heart rhythm caused by abnormal electrical impulses. Depending on which area of the heart is experiencing fibrillation, it may be very serious.
Chaotic, high rate unsynchronised vibrations of the myocardium, resulting in absent or ineffectual pumping.
Rapid irregular contractions of the heart.
An abnormal heart rhythm in which the normal, rhythmic beating of the heart is replaced by disorganized, ineffective and extremely rapid electrical impulses. The state of fibrillation prevents the heart chamber that is fibrillating from having any effective contractions.
Rapid twitching of muscle fiber
Chaotic, high-rate, unsynchronized quivering of the myocardium resulting in ineffectual cardiac pumping.
A quivering of the heart muscle.
can be atrial or ventricular. Ineffective beats.
Abnormal uncontrolled rapid contraction of the fibers in the heart. When the process involves the two upper chambers of the heart (the atria), the condition is called "atrial fibrillation." When it involves the lower, ventricular chambers, the condition is called "ventricular fibrillation."
Rapid, uncoordinated contractions of chambers of the heart.
Erratic electrical activity of the heart. Atrial fibrillation, or erratic electrical activity of the upper chambers, causes irregular contraction of the lower chamber and palpitations, characterized by the feeling of galloping horses. Although palpitations can be disconcerting, atrial fibrillation is generally not a serious condition. Ventricular fibrillation, contrastly, results in inefficient pumping of the lower chamber and can cause death if it is not treated immediately.
Rapid, chaotic heart beats that makes the heart ineffectively in pumping blood. It can affect with the atria (atrial fibrillation) or ventricles (ventricular fibrillation).
In the heart, a series of uncoordinated and continuously repeated contractions in atrium and/or ventricle. Fatal when occurs in ventricle unless rapidly reversed by cardioversion.
