ABSTRACT
We present a case of acute left main coronary artery (LMCA) occlusion that manifested cardiogenic shock and an ST-segment elevation myocardial infarction (STEMI) electrocardiographic (ECG) pattern comprising "triangular" or "lambda-like" QRS-ST-T complexes. The presenting ECG pattern was misinterpreted as ventricular tachycardia (VT) with resultant delayed emergency percutaneous coronary intervention. The patient died of intractable cardiogenic shock. This case corroborates previous research findings associating the ECG pattern comprising "triangular" or "lambda-like" QRS-ST-T complexes observed in the clinical setting of acute myocardial ischemia with acute LMCA occlusion. Also, we demonstrate how this ECG pattern should be scrutinized for ST-segment elevation in order to avoid misdiagnosing a STEMI for VT.
