Is this inferor STEMI? Tachycardia and ST Elevation. Atrial Flutter with Inferior STEMI? Inferolateral ST elevation, vomiting, and elevated troponin The treating team did not identify the flutter waves and they became worried about possible "STEMI" (despite the unusual clinical scenario). Long-term outcome is unknown.

In other words, after reperfusion therapy for STEMI, the appearance of AIVR is usually a good sign, meaning that the artery is reperfused. Our electrophysiologist, Rehan Karim, states he has ablated AVNR"T" ("T" because it is not tachycardia) in a 90 year old, and that he has seen rate-related BBB at very slow rates.

Here is the ECG: Sinus tachycardia. So the real QT is shorter, but the computer does not mention the U-wave, and the U-wave is as important as the T-wave in predicting cardiac dysrhythmias. This patient presented with severe DKA. What do you think? The computer and physician reader wrote: "ST depression, consider subendocardial injury."

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?

Opinions vary widely on the K level at which a patient must be admitted on a monitor because of the risk of ventricular dysrhythmias. My rationale is that if the K is affecting the ECG, then it is affecting the electrical milieu and can result in serious dysrhythmias. Until some real data is available, my opinion is this: 1.

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. Look at the aortic outflow tract. What do you see? Answer below in the still shot.

Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? Comments: STEMI with hypokalemia, especially with a long QT, puts the patient at very high risk of Torsades or Ventricular fibrillation (see many references, with abstracts, below). There is atrial fibrillation.
