Final answer:
Ventricular fibrillation is the life-threatening ventricular dysrhythmia that leads to quivering ventricle walls and no cardiac output, treatable with defibrillation.
Step-by-step explanation:
The ventricular dysrhythmia where the ventricle walls are quivering, preventing any movement of blood out of the ventricles and resulting in no cardiac output, is known as ventricular fibrillation. This is a critical condition where the electrical activity of the heart is highly disordered, causing the ventricles to fail at pumping blood effectively, which can rapidly lead to brain death if not treated within a few minutes. Defibrillation is the most common treatment, which
