Survival rate 17% (out of hospital), 46% (in hospital) ... Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart ...
The survival of PVF largely depends on the promptness of defibrillation. The success rate of prompt defibrillation during monitoring is currently higher than 95%. [8] It is estimated that the success rate decreases by 10% for each additional minute of delay. [citation needed]
Due to ventricular fibrillation and resultant cessation of the cardiac output to vital organs, commotio cordis has a high fatality rate, indicated by two studies to be 72–75 percent, with survival decreasing substantially if effective resuscitation was not performed within three minutes of the impact event.
According to a 2009 literature review of commotio cordis published in Sports Health, resuscitation within 3 minutes resulted in a survival rate of 25%, and that rate dropped to 3% when ...
The overall rate of survival among those who have OHCA is 10%. [135] [136] Among those who have an OHCA, 70% occur at home, and their survival rate is 6%. [137] [138] For those who have an in-hospital cardiac arrest (IHCA), the survival rate one year from at least the occurrence of cardiac arrest is estimated to be 13%. [139]
Rearrest may reduce the likelihood of survival when compared to patients who have had just one episode of cardiac arrest. [3] Overall resuscitation rates have been estimated to be about 34%, [4] however survival to hospital discharge rates are as low as 7%. [1] This phenomenon may be contributed to rearrest.

Most adults who can be saved from cardiac arrest are in ventricular fibrillation or pulseless ventricular tachycardia, which means their heart has fallen out of rhythm. [14] Early defibrillation is the link in the chain most likely to improve survival since defibrillation can help shock the heart back into a regular beat. [15]
Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21 and ...
