Post cath ECG: Now there are hyperacute T-waves again, and recurrent ST depression in V2 This ECG would normally diagnostic of OMI until proven otherwise No further troponins were measured, but it looks like there is recurrent OMI Next day: A CT Coronary Angiogram was done (CTCA) CARDIAC MORPHOLOGY AND FUNCTION: 1. IMPRESSION: 1.

Will you accept this patient for emergent coronary angiogram based on the ECG changes? ischemia) or it can be secondary to abnormal depolarization (e.g Discussion: The ECG in today's case does not have typical ST depression vector of diffuse subendocardial ischemia. How would you interpret the ST changes seen in this ECG?

By the P s, Q s, 3 R Approach ( as reviewed in ECG Blog #185 ): The Q RS complex is obviously wide. CT coronary angiogram — No obstructive coronary disease. CT coronary angiogram showed no obstructive coronary disease. ECG Blog #185 — Systematic P s, Q s, 3 R Approach to Rhythm Interpretation.

This was sent by an undergraduate (not yet in medical school, but applying now) who works as an ED technician (records all EKGs, helps with procedures, takes vital signs) and who reads this blog regularly. This EKG is diagnostic of transmural ischemia of the inferior wall. Edited by Smith He also sent me this great case.

The ECG does not show any definite signs of ischemia. IMPRESSION: The finding of sinus bradycardia with 1st-degree AV block + marked sinus arrhythmia + the change in PR interval from beat #5-to-beat #6 — suggests a form of vagotonic block ( See My Comment in the October 9, 2020 post in Dr. Smith's ECG Blog ).

There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus. [1] It’s judicious, then, to arrange for coronary angiogram.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.
