“…Within 2 minutes of arrest, two thirds of patients have electrocardiographic evidence of ventricular fibrillation or tachycardia,1 but the probability of a rhythm being amenable to defibrillation declines over time 2. Even when an ambulance meets its target response time, some delay between the emergency telephone call and attendance is inevitable.…”

“…This is largely because about 1/3 of cardiac arrests begin as asystole (flat-line). 17,18 Also, it is difficult to defibrillate with continuous ischemia as that ischemia often re-induces VF. (Note the dramatic difference vs. the essentially 100% success rate from immediate defibrillation seen with electrically-induced VF).…”

Accidental electrocutions kill about 1000 individuals annually in the USA alone. There has not been a systematic review or modeling of elapsed time duration defibrillation success rates following electrically-induced VF. With such a model, there may be an opportunity to improve the outcomes for industrial electrocutions and further understand arrestrelated-deaths where a TASER ® electrical weapon was involved. We searched for MedLine indexed papers dealing with defibrillation success following electrically-induced VF with time durations of 1 minute or greater post VF induction. We found 10 studies covering a total of 191 experiments for defibrillation of electrically-induced VF for postinduction durations out to 16 minutes including 0-9 minutes of pre-shock chest compressions.The results were fitted to a logistic regression model. Total minutes of VF and use of pre-shock chest compressions were significant predictors of success (p < .00005 and p = .003 respectively). The number of minutes of chest compressions was not a predictor of success. With no compressions, the 90% confidence of successful defibrillation is reached at 6 minutes and the median time limit for success is 9.5 minutes. However, with pre-shock chest compressions, the modeled data suggest a 90% success rate at 10 minutes and a 50% rate at 14 minutes.1 BACKGROUND In the 1600s an accepted treatment for canine-induced rabies was a post facto pseudo-vaccination:

“…[11][12][13][14] The overwhelming majority of eventual survivors come from this group. [15][16][17][18] If the definitive treatment for these arrhythmias-defibrillation-can be implemented promptly a perfusing cardiac rhythm may be restored and lead to long term survival.…”
