#CME #ESSAY Ventricular Fibrillation IMPORTANT INFORMATION About Ventricular Fibrillation (VF) Ventricular fibrillation is thought to have three phases. These are time sensitive being 1. Electrical Phase 2. Circulatory Phase 3. Metabolic Phase 1. #Electrical phase: - Occurs within first 5 minutes. - Early defibrillation during this time is key and is the basis for providing access to *AED* in public areas (such as airports and stadiums). 2. #Circulatory phase - This Follows the electrical phase
