He interprets here: "This EKG is diagnostic of right bundle branch block and transmural ischemia of the anterior wall, most likely from an occlusion of the proximal LAD. Pendell Meyers had not started medical school by summer of 2012, but he had read every one of my blog posts over the preceding 4 years. He was a paramedic at the time.

There may be ischemia present, but it is not evident on the ECG. In this paper, Dr. Birnbaum writes: "In patients with ACS without LVH, ST depression with negative T waves in the lateral leads is a sign of sub-endocardial ischemia and is an independent predictor of adverse outcome [11 – 13]. ST elevation in V2 is about 3.5

Mechanism is thought to be due to sustained sympathetic stimulation, probably caused by dysfunction of insular cortex resulting in reversible neurogenic damage to the myocardium which could include contraction bands and subendocardial ischemia [2]. 2012 Dec;7(4):290-4. 2012 Dec;7(4):290-4.

The ECG does not show any definite signs of ischemia. Uncontrolled coronary spasm may be associated with serious arrhythmias , including cardiac arrest ( Looi et al — Postgrad Med, 2012 ; Tan et al — Eur Heart J Case Rep, 2018 ; Chevalier et al — JACC, 1998 ; Rodriguez-Manero — EP Europace, 2018 ). He denied any exertional chest pain.

Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. The ECG does not show any signs of ischemia. True Positive ECG#2 : Also sinus rhythm. There is ST depression in V1.

Traditional methods of non-invasive ischemia testing (stress EKG , stress echo, SPECT , PET , direct-to-cath) can result in false negatives 20-30 percent of the time, which can lead to undetected disease, and false positives over 50 percent of the time, which can lead to unnecessary invasive procedures.
