Occlusion myocardial infarction is a clinical diagnosis

Dr. Smith's ECG Blog

DECEMBER 11, 2023

Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." Case continued She was loaded with aspirin 325 mg, and repeat troponin drawn around the time of EKG 1 resulted at 267 ng/L. At midnight.

DECEMBER 19, 2023

link] A 62 year old man with a history of hypertension, type 2 diabetes mellitus, and carotid artery stenosis called 911 at 9:30 in the morning with complaint of chest pain. Challenge QUESTION: The relative change in T-QRS-D is not the only thing that changes during period of time that passed between recording of the 2 ECGs shown in Figure-1.

Post Cath ECG: Obviously completing MI with LVA morphology, and STE that meets STEMI criteria (but pt is still diagnosed as "NSTEMI"). Day 12 ECG: FINAL DIAGNOSIS: "NSTEMI" Despite the fact that his day 4 ECG easily meets STEMI criteria, the patient is diagnosed as NSTEMI. Academic Emergency Medicine 27(S1): S220; May 2020.

Two recent interventions have proven in randomized trials to improve neurologic survival in cardiac arrest: 1) the combination of the ResQPod and the ResQPump (suction device for compression-decompression CPR -- Lancet 2011 ) and 2) Dual Sequential defibrillation.

As always, LAD OMI need not meet STEMI criteria and usually does NOT! Here are many examples which we have already posted: 5 of LVH mimicking Precordial Swirl 1 case (Case 6) of LVH mimicking precordial swirl, but it is actually LVH + posterior OMI 14 Cases (Cases 7-20) of OMI with Precordial Swirl First, 5 mimics: Case 1.

Chest pain and shock: Is there a right ventricular OMI on this ECG? And should he undergo trancutaneous pacing?

Dr. Smith's ECG Blog

MAY 30, 2023

There is an obvious inferior posterior STEMI(+) OMI. We recorded an ECG in which V1-V3 were put in the position of V4R-V6R, and V4-6 were placed in V7-9 to (academically) confirm posterior OMI. 1 mg of Atropine was given and the heart rate increased transiently to 60. What is the atrial activity? How would one tell? What to do?

There is STE in III and aVF which does not meet STEMI criteria due to insufficient STE in lead aVF. The interventionalists insisted that the ECGs did not meet STEMI criteria and cancelled the activation, stating that they would consider urgent cath after further stabilization. This is an obvious inferoposterior OMI. mm STE with 9.5

Another deadly and confusing ECG. Are you still one of the many people who will be fooled by this ECG, or do you recognize it instantly?

MAY 5, 2022

Despite the clinical context, Cardiology was consulted due to concerns for a "STEMI". Hyperkalemia mimics STEMI and OMI in many distributions, but probably the most common is the Brugada morphology in V1-V2 which mimics anterior OMI for those who cannot recognize the Brugada pattern. Limb lead reversal can be easily recognized.
