In this large trial of almost 10,000 out-of-hospital cardiac arrest victims, they were randomized to early (within 60 seconds) rhythm analysis or delayed (180 seconds, to improve cardiac perfusion before a shock). The outcome (survival to hospital discharge with functional recovery) was only 6% in both groups, with no difference between groups. There is no advantage to delaying rhythm analysis is out-of-hospital cardiac arrest victims (abstract)
