The ECG told the whole story, but no one listened: ECG interpretation skills are critical to patient outcomes.

Was there pulmonary edema? Repeat ECG showing no STEMI, only non-specific ST-segment and T-wave abnormalities, unchanged from prior" Transferred to surgery for exploration but diagnostic studies were too indeterminate to be certain of intra-abdominal pathology. There is a junctional bradycardia. Now chest pain free.

31 Year Old Male with RUQ Pain and a History of Pericarditis. Submitted by a Med Student, with Great Commentary on Bias!

Without seeing the patient, my interpretation of the first ECG was: likely normal variant ST-elevation (early repolarization), with a small possibility of pericarditis, and almost no possibility of acute coronary occlusion (STEMI). and therefore highly unlikely to be STEMI. The ST/T ratio in V6, however, is slightly greater.

Tachycardia, fever to 105, and ischemic ST Elevation -- a Bridge too Far

Dr. Smith's ECG Blog

A prehospital ECG was recorded (not shown and not seen by me) which was worrisome for STEMI. A previous ECG from 4 years prior was normal: This looks like an anterior STEMI, but it is complicated by tachycardia (which can greatly elevate ST segments) and by the presentation which is of fever and sepsis.

1 hour of CPR, then ECMO circulation, then successful defibrillation.

There is sinus bradycardia with one PVC. This is a troponin I level that is almost exclusively seen in STEMI. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest had another etiology (such as old scar), and the ST elevation is due to severe shock, then it is a type II STEMI. myocarditis).

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? There is also bradycardia. The corrected QT interval is extremely long, about 500 ms.

On his physical examination, cardiac and pulmonary auscultation was completely normal. His first electrocardiogram ( ECG) is given below: --Sinus bradycardia. Bi-phasic scan showed no dissection or pulmonary embolism. Take home messages: 1- In STEMI/NSTEMI paradigm you search for STE on ECG. Turk Kardiyol Dern Ars.

Syncope, Shock, AV block, Large RV, "Anterior" ST Elevation.

Dr. Smith's ECG Blog

In any case, there is bradycardia. It makes pulmonary embolism (PE) very likely. The small LV implies very low LV filling pressures, which implies low pulmonary venous pressure. LV anterior STEMI does not give maximal ST elevation in V1. So this ECG is typical of right ventricular (RV) STEMI.
