See these 2 articles Association between pre-hospital chest pain severity and myocardial injury in ST elevation myocardial infarction: A post-hoc analysis of the AVOID study Author links open overlay panel [link] 1 Background We sought to determine if an association exists between prehospital chest pain severity and markers of myocardial injury.

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.

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.

indicates inducible ischemia while an FFR above 0.80 excludes ischemia in 90% of cases. They had lower rates of mortality or myocardial infarction. myocardial infarction rate and 3.2% There is a strong correlation between FFR and inducible myocardial ischemia. Normal FFR is 1.0 An FFR below 0.75

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.

This ECG is diagnostic of diffuse subendocardial ischemia. Methods: Between June 2007 - July 2009 all NT-OHCA patients aged >18, transported to our hospital, an urban, level one trauma teaching hospital were included. Chicago November 2010. Conclusions: Head CT is common in NT-OHCA.

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.
