Contact-to-ECG time, time between emergency medical technicians (EMT) arrival and first ECG performed; Contact-to-Door time, time between EMT arrival and patient arrival at the hospital; Contact-to-Balloon time, time between EMT arrival and restoration of coronary artery blood flow; RCA, right coronary artery; LM, left main coronary artery; LAD, left anterior descending artery; ECMO, extra-corporeal membrane oxygenation; LCX, left circumflex artery; VT/VF, ventricular tachycardia/ventricular fibrillation; DC, direct current; IABP, intra-aortic balloon pump; OHCA, out-of-hospital cardiac arrest; MI, myocardial infarction; PPCI, primary percutaneous coronary intervention.
