Incidence of EMS-Treated OHCA
Incidence and survival rate per emergency medical services (EMS)–treated out-of-hospital cardiac arrest (OHCA) of presumed cardiac etiology (A) and with ventricular fibrillation (B).40 The incidence of EMS-treated OHCA of presumed cardiac etiology was higher in North America (54.6) than in Europe (35.0), Asia (28.3), and Australia (44.0) (P < 0.001). The incidence of EMS-treated OHCA with ventricular fibrillation was lower in Asia (3.2) than in Europe (12.8), North America (14.0), and Australia (14.9) (P < 0.001). ∗P < 0.05 and ∗∗∗P < 0.001.
