Ventricular fibrillation
Ventricular fibrillation is a cardiac condition which consists of a lack
of coordination of the contraction of the muscle tissue of the large
chambers of the heart. The ventricular muscle twitches randomly, rather
than contracting in unison, and so the ventricles fail to pump blood
into the arteries. Ventricular fibrillation is a medical emergency.
Clinical picture
If this arrhythmia continues for more than a few seconds, the blood
pressure will collapse, blood circulation will cease, and death will
ensue.
Ventricular fibrillation is one cause of cardiac arrest. Countering it
is a major goal of advanced cardiac life support.
Treatment
This condition can sometimes be reversed with the use of a
defibrillator.
