Identifying the infarct-related artery (IRA) in a non-ST-segment-elevation acute myocardial infarction (NSTEMI) can be very challenging, particularly in a hospital that cannot perform intracoronary imaging due to certain limitations. This is because, by angiography, most patients present with multivessel coronary artery disease (CAD), diffuse disease, or non-significant CAD. We present a case of a 60-year-old female patient presented with substernal chest pain and palpitations of 6 hours duration. The first hospital contacts 12-lead electrocardiogram (ECG) showed ventricular tachycardia (VT) with unstable hemodynamics, after stabilization patient was transported to the catheterization laboratory for immediate percutaneous coronary intervention (PCI). With a clue of VT morphology, post-converted ECG, and coronary angiography, the patient successfully underwent PCI in the left circumflex artery.
