An undergraduate who is an EKG tech sees something. The computer calls it completely normal. How about the physicians?

Dr. Smith's ECG Blog

This EKG is diagnostic of transmural ischemia of the inferior wall. If it is angina, lowering the BP with IV Nitroglycerine may completely alleviate the pain and the (unseen) ECG ischemia. Transmural ischemia (as seen with the OMI findings on ECG) is not very common with demand ischemia, but is possible.

See this "NSTEMI" go unrecognized for what it really is, how it progresses, and what happens

Dr. Smith's ECG Blog

A man in his 70s with past medical history of hypertension, dyslipidemia, CAD s/p left circumflex stent 2 years prior presented to the ED with worsening intermittent exertional chest pain relieved by rest. The baseline ECG is basically normal with no ischemia. In my opinion, I think it looks more like subendocardial ischemia.

First ED ECG is Wellens' (pain free). What do you think the prehospital ECG showed (with pain)?

Dr. Smith's ECG Blog

A stent was placed. For those who depend on echocardiogram to confirm the ECG findings of ischemia, this should be sobering. In this case, the duration of ischemia was so brief that there was no such evolution, and there was near-normalization. Ischemia may be so brief that Wellens' waves do not evolve 3. Lessons: 1.

Precordial ST depression. What is the diagnosis?

Dr. Smith's ECG Blog

A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.

Is OMI an ECG Diagnosis?

Written by Jesse McLaren A 70 year old with prior MIs and stents to LAD and RCA presented to the emergency department with 2 weeks of increasing exertional chest pain radiating to the left arm, associated with nausea. 1] European guidelines add "regardless of biomarkers". But only 6.4%

Why we need continuous 12-lead ST segment monitoring in Wellens' syndrome

Dr. Smith's ECG Blog

The ECG in the chart was read as "no obvious ST changes," (even though no previous ECG was available) and the formal read by the emergency physicians was: "ST deviation and moderated T-wave abnormality, consider lateral ischemia." It was stented. Comment: most T-wave inversion is nonspecific, but not these ones! Gottlieb SO, et al.

Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. The lesion was stented. It they are static, then they are not due to ischemia. This is better evidence for ischemia than any other data point. Again, cath lab was not activated. Int J Cardiol.
