Diffuse ST depression with ST elevation in aVR: Is this pattern specific for global ischemia due to left main coronary artery disease? Ischemia b. ST depression: is it ischemia? It was a baseline finding in 62% of patients, usually due to LVH. Reference: Knotts RJ , Wilson JM, Kim E, Huang HD, Birnbaum Y.

Angiogram --Minimal coronary atherosclerosis --No obstructive epicardial coronary artery disease or evidence of plaque rupture noted to explain prolonged QT or ventricular fibrillation cardiacarrest, suspect nonischemic mechanism Echo The estimated left ventricular ejection fraction is 45 %. Acute ischemia?

The first task when assessing a wide complex QRS for ischemia is to identify the end of the QRS. The ST segment changes are compatible with severe subendocardial ischemia which can be caused by type I MI from ACS or potentially from type II MI (non-obstructive coronary artery disease with supply/demand mismatch).

There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( If there had been ECG findings indicating reocclusion of the artery — an angiogram would have been warranted ).

A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Poor blood supply Ischemia, or inadequate blood supply to the heart, is an abnormality that can be detected in an ECG test. ECG machine can also help diagnose coronary artery disease.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI. It is possible there is microvascular dysfunction producing residual transmural ischemia. Circumstances attending 100 sudden deaths from coronary artery disease with coroners necropsies.
