Final answer:
An AED, or automatic external defibrillator, is a life-saving device used to correct ventricular fibrillation during a cardiac arrest by delivering an electrical shock. These devices are accessible in public places and are designed to be used by nonmedical personnel with verbal instructions provided. CPR is often advised before AED usage to maintain patient stability.

Understanding the Usage of Posterior Paddle Assembly in Defibrillators
Defibrillators can be the difference between life and death for a person experiencing cardiac arrest due to ventricular fibrillation. An external automatic defibrillator, or AED, can help reestablish a normal sinus rhythm. While defibrillator paddles are often seen in hospitals, automated external defibrillators have become more accessible, and are now found in many public places and carried by ambulances. These AEDs, which come with verbal instructions, make it possible for nonmedical personnel to provide prompt care in critical situations. Key to their function is an electrocardiogram that analyzes heart rhythms and delivers an electrical shock with appropriate energy to reset the heart's rhythm. When an arrhythmia occurs, the precipitated heart attack can often be stopped by applying a significant electric shock, allowing the body's internal pacemaker to restore a normal rhythm. Furthermore, before utilizing an AED, CPR is commonly recommended to sustain the patient until the rhythm can be corrected.
