He had episodes of chest pain off and on all night, until about 1 hour prior to arrival when the pain became constant, crushing, 10/10 chest pain that radiated to both arms. Barely any STE, and thus not meeting STEMI criteria. Only now that the patient has STEMI criteria is he allowed to go to the cath lab, at around 0530.

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.

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?

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. Here is his triage ECG: There is massive STE in V3-V6, and also STE in II, III, aVF. Why is this important?

And so it is wise to look at the coronary arteries. Here they are: Learning Points: 1. This ECG certainly looks like myocarditis, and was due to myocarditis, but missing acute coronary occlusion is not acceptable. 12 All STEMI patients had very high cTn typical of STEMI (cTnT > 1.0 Angiogram was negative.

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. the presence of such well developed, wide, anterior Q-wave suggests completed transmural STEMI. Lessons : 1.

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.

Is this due to coronary occlusion? The medic activated the cath lab but was refused by the interventionalist, who did not believe that this ECG represented acute coronary occlusion. Important Learning Point: "STEMI" is defined by millimeter criteria (1 mm in limb leads), which this does not meet. Why did I say this?

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.

Not quite a STEMI, but same effect.) There is ST elevation in V2-V4 that does not quite meet "STEMI criteria." That is a reasonable thought, but we have shown that if there is one lead of V1-V4 with a T/QRS ratio greater than 0.36, then it is STEMI, not LV aneurysm. Is this a transient STEMI? Learning Points: 1.
