Analysis highlights impact of rapid first shock after cardiac arrest

Research from Amsterdam UMC analyzed the data of 3,723 out-of-hospital cardiac arrest patients and found that for the first shock, every minute of delay reduces the chance of survival by 6%. Giving the first shock within six minutes resulted in a 93% chance of stopping the heart rhythm disorder ventricular fibrillation, compared to 75% when the shock was delayed beyond 16 minutes. The study emphasizes the importance of quickly administering the first shock after a cardiac arrest to improve survival rates. Efforts to shorten the time from the emergency call to the first shock can significantly impact outcomes.
