Final answer:
In pulseless VTach or VFib, defibrillation is used to restore the heart's normal rhythm.
Step-by-step explanation:
In the event of pulseless ventricular tachycardia (VTach) or ventricular fibrillation (VFib), the primary goal is to restore the heart's normal rhythm, as both conditions are life-threatening. The most common treatment for these conditions is defibrillation, which involves delivering a large electrical shock to the heart using special paddles or automated external defibrillators (AEDs). This shock helps to reset the heart's electrical activity and allows it to resume normal beating.
