ST elevation (STE) in lead augmented vector right (aVR), coexistent with multilead ST depression, was endorsed as a sign of acute occlusion of the left main or proximal left anterior descending coronary artery in the 2013 STEMI guidelines. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ).

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

Other trials that evaluated this subject were the WOEST trial (2013), Pioneer AF-PCI trial (2016), and ISAR-TRIPLE (2015). His exam was notable for tachycardia, elevated jugular venous pressure, diffuse rales, and an early 2/6 systolic murmur loudest at the cardiac apex. These are the main aspects of the findings related to this trial.

Here is another proven left main occlusion in a young woman who presented with sudden pulmonary edema, had this ECG recorded, then arrested and was resuscitated after 30 minutes of CPR: This has sinus tachycardia with RBBB and LAFB, and STE in V2-V6 as well as I, aVL This pattern could just as easily be seen in LAD occlusion.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct.
