The morphology of V2-V4 is very specific in my experience for acute right heart strain (which has many potential etiologies, but none more common and important in EM than acute pulmonary embolism). CT angiogram showed extensive saddle pulmonary embolism. He had multiple cardiac arrests with ROSC regained each time.

Notice I did not say "pulmonary embolism," because any form of severe acute right heart strain may produce this ECG. This includes, but is not limited to, PE, asthma/COPD exacerbation, hypoxic vasoconstriction from pneumonia, acute pulmonary hypertension exacerbation. Differences of Pulmonary Embolism T-waves from Wellens' T-waves: 1.

My answer: "This is classic for PE, but it can also be present in any hypoxia due pulmonary hypoxic vasoconstriction and resulting acute pulmonary hypertension and acute right heart strain. Tachycardia (or nearly) 2. An ECG was texted to me (Smith) without any clinical information: What did I say? This is NOT Wellens.

The patient was transported to the CCU for further medical optimization where a pulmonary artery catheter was placed. In cardiogenic shock, fluid may worsen the pulmonary edema associated with acute heart failure, but may still be required to support the hemodynamic status of the patient. The mean MAP for these patients was 81 +/- 13.

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. Fourth, syncope in the elderly often results from polypharmacy and abnormal physiologic responses to daily events. of ED visits.

For right or wrong reasons, the world of electrophysiology has pushed us into a belief system that, if it is AF, the culprit must be pulmonary veins. In fact, non-pulmonary vein origins can be a staggering 70% in some series. If we look at the above map,RA prevails over LA convincigly in termes of focal atrial tachycardia.
