An initial electrocardiogram (ECG) is provided below. While the initial impression might not immediately suggest ventricular tachycardia (VT), a closer examination raises suspicion. His current medication regimen includes apixaban, carvedilol, perindopril, spironolactone, torasemide, dapagliflozin, amiodarone, and ivabradine.

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.

Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults. Ventricular arrhythmias during exercise can be documented in congenital long QT syndromes as well as in catecholaminergic polymorphic ventricular tachycardia.

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]. Lead electrocardiogram changes after supratentorial intracerebral hemorrhage.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

ECG in a person with persistent anginal pain for the past several hours showing significant ST segment depression anterolateral leads along with sinus tachycardia. ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum. J Am Coll Cardiol.

These findings are concerning for inferior wall ischemia with possible posterior wall involvement. You will note that it is essentially an unremarkable electrocardiogram except for some PACS. C linically — the rhythm we see in the long lead II of ECG #3 behaves similar to MAT, even though there is no tachycardia.
