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]. Electrocardiographic changes in intracranial hemorrhage mimicking myocardial infarction.

Precordial ST depression may be subendocardial ischemia or posterior STEMI. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. Whether it is subendocardial ischemia or posterior STEMI, if you cannot get it to resolve, you must activate the cath lab. There is no ST elevation.

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

He was found diaphoretic and uncomfortable, and verbalizing a prior history of myocardial infarction and that, furthermore, the acute symptoms were identical to that which had been associated with RCA stent placement 4 years prior. Terminal QRS distortion is present in anterior myocardial infarction but absent in early repolarization.
