In the days before I learned to look for OMI, back when I was counting ST elevation boxes, I used to save ischemia for last.) The atrial rate is around 120 beats per minute, which indicates high adrenergic state and physiologic distress! Never forget that sinus tachycardia is the scariest arrhythmia. The rate is near 80, normal.

This is critical for the EMS provider, or ED clinician, as identification of Grade I ischemia (aka, HATW’s) addresses the culprit lesion at the earliest opportunity with excellent downstream prognosis for the patient. [2] 2] But there is also Sinus Tachycardia! Chapter 6: Introduction to Myocardial Ischemia and Infarction.

The ECG was incorrectly interpreted as no signs of ischemia. Artificial intelligence can be trained to recognize subtle OMI = My Comment by K EN G RAUER, MD ( 2/6 /2023 ): = The initial ECG in today's case was incorrectly interpreted as, "No signs of ischemia". There is sinus tachycardia at 100-105/minute.

Although the shock is no doubt partly a result of poor pump function, with low stroke volume, especially of the RV, it should be compensated for by tachycardia. RCA ischemia often results in sinus bradycardia from vagal reflex or ischemia of the sinus node. This is a perfect indication for atropine.

No evidence for ischemia jumps out. Conduction system pacing" is a newer technique that is being studied as a way of delivering more physiologic pacing, typically by inserting a lead into the area of the left bundle branch, or the bundle of His. So the most likely rhythm in ECG 1 is ectopic atrial tachycardia.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Evidence of acute ischemia (may be subtle) vii. Most physicians will automatically be worried about these symptoms. Left BBB vi.

It doesn’t require any extraordinary intelligence to conclude any chronic focal atrial tachycardia can get degenerated to AF in the long run. In that case, the famous atrial tachycardia localizing map from Peter Kistler et al from Australia JACC 2006 holds good for location AF focus too. Reference 1. Francis Marchlinski Cory M.

It is possible there is microvascular dysfunction producing residual transmural ischemia. But this is most common when there is prolonged ischemia, and this patient had the fastest reperfusion imaginable!
