@drlfarrell not my area, but uk data suggest:
❤️&lt;10%/20% survival if out of/in hospital
❤️better if rhythm is 'shockable'
❤️ "        "      is rapid for this group
❤️survival to leave hospital isn't the same as going home or becoming well - sig number have brain injury
❤️worse with age https://t.co/7lfkidagql
