A rapid echocardiogram was performed, revealing an ejection fraction of 20% with thinning of the anterior-apical walls. Learning Point: Concordant ST segment elevation can arise from profound ischemia triggered by ventricular tachycardia (VT), or it may represent an exaggerated basal ST change accompanying tachycardia.

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.

A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. 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.
