Ventricular fibrillation is a life-threatening cardiac arrhythmia in which the heart's ventricles, the lower chambers responsible for pumping blood to the body, quiver or fibrillate instead of contracting normally. This results in the heart being unable to pump blood effectively, leading to a lack of oxygen to the body's vital organs.

During ventricular fibrillation, the heart's electrical impulses become disorganized, causing the ventricles to contract in a rapid, irregular and uncoordinated manner. The chaotic electrical activity results in the ECG waveform appearing as irregular, rapid and disorganized waves, known as fibrillatory waves. The absence of a normal QRS complex, which represents the ventricular depolarization, is a key characteristic of ventricular fibrillation.
