Ventricular fibrillation (VF) is a cardiac dysrhythmia that cannot produce a pulse. In VF, the heart's electrical activity becomes chaotic, preventing it from effectively pumping blood. As a result, there is no measurable blood flow or pulse, leading to a critical lack of oxygenated blood to vital organs. Immediate intervention, such as defibrillation, is required to restore a normal rhythm and pulse.
