The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. However, he suddenly developed a series of malignant ventricular arrhythmias. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.

There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. It is a benign arrhythmia which requires no specific treatment. The receiving emergency physician consulted with interventional cardiology who stated there was no STEMI. Moffat, M.

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? malignant ventricular arrhythmias are present), rapid replacement of potassium is required.

This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. This was diagnosed by IVUS (intravascular ultrasound) as a ruptured plaque. This finding is easy to overlook because of the lack of a long lead II … Perhaps this marked sinus arrhythmia reflects increased vagal tone? It was stented.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

On intravascular ultrasound (IVUS), the mid RCA plaque was described as "cratered, inflamed, and bulky," and the OM plaque was described as "bulky with evidence of inflammation and probably ulceration." Additional findings: No ST elevation." They also documented "Reproducible chest tenderness."

On arrival, the patient was in shock, was intubated, and had an immediate cardiac ultrasound. What does a heart look like on ultrasound when the EKG looks like that? Here you go: It's not the world's greatest cardiac ultrasound video, but it does appear to show poor function and low volume. They transported to the ED.
