Methods Here, a mathematical and physiological framework to define the patient-specific tipping point of myocardial energetics is defined. A novel hemodynamic parameter known as the myocardial performance score (MPS), a marker of power and efficiency, is introduced that allows for the objective assessment of the physiological tipping point.

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.

The patient was transported to the CCU for further medical optimization where a pulmonary artery catheter was placed. Authors' commentary: Cardiogenic shock in the setting of severe aortic stenosis. Fundamentally, cardiogenic shock is an issue of decreased cardiac output.

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 is unusual in ACS unless there is cardiogenic shock or a second simultaneous pathology. This is NOT Wellens.
