-- V fib

-- disorganized quivering of the ventricles

-- ineffective

-- no blood is pumped through body

-- patient usually becomes unconscious within seconds

-- only way to fix is to defibrillate

-- defibrillation      -- shocking the heart      -- “resets” the heart      -- restores normal beat

-- defibrillation is highly successful if given quickly

-- if defibrillation is not available, begin CPR

Medicine Resident Slaps Monitor Hoping V-Fib is Just Artifact

http://gomerblog.com/wp-content/uploads/2017/08/67961135_m-e1496603382648.jpg

ATLANTA, GA - Implementing an often overlooked early step in the ACLS algorithm, third-year Emory University internal medicine resident Carrie-Ann Winslow slapped the monitor at the patient's bedside in the slim chance that the ventricular fibrillation (v-fib) is just some form of...

Cardiopulmonary resuscitation (CPR) and early defibrillation are essential for managing cardiac arrest. Defibrillation, which interrupts chaotic myocardial electrical activity, has traditionally been performed using an automated external defibrillator (AED) with pads in the anterolateral position. However, in cases of refractory ventricular fibrillation (VF), the effectiveness of this technique may decrease, leading to the exploration of alternatives such as defibrillation vector change. This strategy aims to improve shock efficacy by redistributing the electric field and promoting synchronized myocardial depolarization. This study aims to analyze the scientific evidence on the impact of defibrillation vector change on rhythm conversion, return of spontaneous circulation (ROSC), and survival in patients with cardiac arrest. A systematic review with a meta-analysis of studies published between 2020 and

2025 was conducted, including randomized clinical trials and observational studies on defibrillation pad positioning. The results indicate that both defibrillation vector change and double sequential external defibrillation (DSED) increase the rate of rhythm conversion and ROSC compared to standard defibrillation. However, the impact on long-term survival remains uncertain. Some studies suggest a

slight improvement in survival with DSED, but no statistically significant difference is observed.
