The "criteria" for posterior STEMI are 0.5 Is it STEMI or NonSTEMI? The patient had no hypertension, no tachycardia, a normal hemoglobin, no drug use, no hypotension/shock, no murmur of aortic stenosis. The 4th, after the opening of the artery and release of troponin from the cardiac circulation, was 99.9

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

Is it ventricular tachycardia (VT) due to hyperK or is it a supraventricular rhythm with hyperK? Here are other posts on hyperK, large calcium doses for hyperK, and ventricular tachycardia in hyperK Weakness, prolonged PR interval, wide complex, ventricular tachycardia Very Wide and Very Fast, What is it? How would you treat?

Here is the ECG: Sinus tachycardia. Discussion See this post: STEMI with Life-Threatening Hypokalemia and Incessant Torsades de Pointes I could find very little literature on the treatment of severe life-threatening hypokalemia. mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0 What else?

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. 2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI.

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. 2 The astute paramedic recognized this possibility and announced a CODE STEMI. Circulation. Circulation 67, No. Circulation 1970;41:623-627 9. What do you see?

This doesn’t meet STEMI criteria so in the current paradigm there’s no urgency to getting an angiogram. The initial ECG suggested either subacute or reperfused inferoposterior occlusion and clearly does not meet traditional STEMI criteria. Discharge diagnosis was ‘STEMI’, even though no ECG ever met STEMI criteria.

The status of the patients chest pain at this time is unknown : EKG 1, 1300: There is sinus tachycardia and artifact of low and high frequency. However, there is also significant tachycardia , with heart rate of 116, and known hypoxia. Supply-demand mismatch can cause ST Elevation (Type 2 STEMI). An EKG was immediately recorded.
