Survival rates for out-of-hospital [[cardiac arrest]]s in North America are poor, often less than 10%.<ref name="medscape" /> Outcome for in-hospital cardiac arrests are higher at 20%.<ref name="medscape" /> Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21 and 50%.<ref name="CriticalCare" /><ref name="Nadkarni" /><ref name="Nichol" />
