Case continued Another ECG was recorded 3 hours later, still 1/10 pain: There is sinus bradycardia with RBBB. So we know there is myocardial infarction and the patient has persistent pain, but it is very mild. The culprit was opened and stented. They only mask the underlying pathology.

Both of these features make inferior + RV MI by far the most likely ( Pseudoanteroseptal MI is another name for this ) There is also sinus bradycardia and t he patient is in shock with hypotension. A narrow complex bradycardia without any P-waves is also likely to respond to atropine, as it may be a junctional rhythm.

Electrocardiographic Criteria to Differentiate Acute Anterior ST Elevation Myocardial Infarction from Left Ventricular Aneurysm. Former resident: "Just saw cath report, LAD stent was 100% acutely occluded." They of course opened and stented it. American Journal of Emergency Medicine 2005; 23(3):279-287.

Here is his ED ECG: There is bradycardia with a junctional escape. Case continued A bedside ultrasound showed diminished LV EF and of course bradycardia. Angiogram: Culprit Lesion (s): Thrombotic occlusion of the proximal RCA -- stented. He appeared gray in color, with cool skin. What is the atrial activity? Worrall , Stephen W.

The ECG shows sinus bradycardia but is otherwise normal. So there is probability of myocardial injury here (and because it is in the correct clinical setting, then myocardial infarction.) On the combined basis of angiography and IVUS, this patient received stents to his mid RCA, proximal PDA, and OM.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. This was stented. The corrected QT interval is extremely long, about 500 ms.

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. No appreciable skin pallor. He reported to be a social drinker, but used tobacco products daily. Here is the time-zero 12 Lead ECG.
