Incidence and outcomes of out-of-hospital cardiac arrest from initial asystole: A systematic review and meta-analysis

Description

We talk a lot about shockable rhythms—but what about asystole? This episode dives into a global meta-analysis of over 540,000 OHCA cases and the results are rough: just 1.5% survive when asystole is the first rhythm.


We break down what this means for EMS, why TOR guidelines matter more than ever, and how we need to rethink the resus game when the rhythm is flatline from the start.


Based on the study by Dwivedi et al. in Resuscitation: Incidence and outcomes of out-of-hospital cardiac arrest from initial asystole.
