Why is the patient in shock? He was in profound cardiogenic shock. 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. There is an obvious inferior STEMI, but what else?

The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. (

Soon afterward, the patient’s symptoms return along with lightheadedness, bradycardia, and hypotension. The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. The Queen of Hearts agrees: Around this time his initial high sensitivity troponin I resulted at 231 ng/L.

Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. The patient died of cardiogenic shock within 24 hours despite mechanical circulatory support. There are also J-waves.

Then the notes mention "cardiogenic shock" but without any reference to a cardiac echo or to a chest x-ray. There is a junctional bradycardia. This is the etiology of the syncope and hypotension and shock and elevated CVP. They were worried that the syncope was seizure and that she had brain mets. What was the diagnosis?
