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]. 2009 Nov;40(11):3478-84. Epub 2009 Aug 27. doi: 10.1161/STROKEAHA.109.556753.

While the initial impression might not immediately suggest ventricular tachycardia (VT), a closer examination raises suspicion. Additionally, the qR morphology, particularly in a patient with right bundle branch block (RBBB) type wide QRS complex tachycardia (WQCT), lends further support for VT. What is the rhythm?

Precordial ST depression may be subendocardial ischemia or posterior STEMI. Notice there is tachycardia. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. V4-V6, is much more likely to be posterior than subendocardial ischemia. 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.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified.
