VF (Ventricular Fibrillation)

Ventricular fibrillation (VF) is a medical emergency that occurs when the heart's lower chambers, or ventricles, experience chaotic electrical activity. Instead of pumping blood effectively, the heart quivers ineffectively, leading to loss of blood flow to vital organs. This can result in sudden cardiac arrest and, if not treated immediately, can be fatal. Treatment typically involves CPR and the use of a defibrillator to restore a normal heart rhythm. Recognizing the signs of VF and acting quickly is crucial for survival.
