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. Figure-1: The initial ECG in today's case — obtained after ROSC.

But these cases show the potential dangers of delayed recognition and treatment of inferior reperfusion Take away 1. Rather than using terms like “STEMI” and “Wellens”, it’s more helpful to describe the underlying pathology and ECG pattern pattern: Occlusion MI, and reperfusion T wave inversion 4.

mm of ST segment elevation, V2 and V3 have 1 mm of elevation, v4 has 2 mm of elevation and v5 around 1.5 Note 1: Levels were significantly lower in takotsubo that presented with T-wave inversion.

Thus, this is BOTH an anterior and inferior STEMI in the setting of RBBB. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. Raitt et al.), Raitt et al.), Armstrong et al.), 3) Oliva et al. (4) Lessons : 1.

A 40-something male presented with dyspnea and left arm numbness, and perhaps some chest tightness, for 1 1/2 hours. This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. Thelin et al. Mokhtari et al. Therefore this is " Transient ST Elevation Unstable Angina."

Here they are: Learning Points: 1. 3–8 Shi et al. 7 These 3 studies, as well as 1 smaller meta-analysis, 6 and another small study, 8 make it clear that troponin is associated with increased severity and mortality in COVID when adjusted for multiple other variables. He remained supported on an intraaortic balloon pump.

There are two main etiologies of ischemic ST-depression: 1) subendocardial ischemia 2) reciprocal to ST-elevation in an opposite wall Here there are distinct R-waves with marked ST-depression throughout most of the precordium. But if there is none - then you are looking at least at an Isolated Posterior STEMI until proven otherwise.

The pattern of STE and STD reminded us of Brugada Type 1 morphology. Smith comment: 1) Brugada ECG may have ST shifts in limb leads as well as precordial leads. 2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. In the largest study looking at this topic by Mizusawa et al.,

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.

I do research on Cardiologs' algorithm: Smith SW et al. S-wave is in V2 = 17 mm S-wave V4 = 9 mm Total = 26 (not greater than 28), so not LVH by the new rule! Peguero JG et al. But lead V2 has a worrisome amount of ST elevation, and in a chest pain patient, I would be worried about STEMI. If the total is greater than 2.3

The neurologic section was divided into (1) brain oxygenation, perfusion, edema, and intracranial pressure (ICP); (2) seizures and the ictal-interictal continuum (IIC); and (3) sedation and analgesia. Authors state early cath may be of benefit in those with no STEMI, but much of the more recent literature suggests this is more controversial.
