P-value Odds ratio (95% CI) P-value Odds ratio (95% CI)
ECG Ischemic ECG 0.127 2.68 (0.76-9.50) < 0.001 30.6 (11.7-80.2)

Factors contributing to the overall assessment of the suspicion of ACS. Ischemic ECG = ST elevation or ST depression or T inversion; LBBB, Left bundle branch block; AF, Atrial fibrillation, AFL, Atrial flutter; PM, pacemaker; TnT+, TnT ≥ 0.05 μg/L.
