patient triage. Specifically, patients should be managed based on the presence or absence of ST-segment elevation (or suspected equivalent) on the 12lead ECG (Table 3 for STEMI electrocardiographic criteria). When possible, electrocardiographic tracings can be transmitted to the PPCI center while en route to help expedite coronary reperfusion upon arrival. Because patients with ACS and evidence of heart failure (HF), ventricular arrhythmias, or cardiogenic shock in the prehospital setting are at highest risk for death, identification of these complications is important with subsequent triage of these patients to a PCI-capable facility when possible (Section 8, “Cardiogenic Shock Management”).14,15

1 The early acquisition and recording of prehospital

12-lead ECGs by trained personnel is associated with shorter reperfusion times and lower mortality rates from STEMI if this diagnostic information is integrated in patients’ care.1,2,16 Appropriately trained EMS personnel (ie, paramedics) can interpret 12-lead ECGs for the identification of STEMI
