A 20-something presented after a huge verapamil overdose in cardiogenic shock. This was a very complex case and the details are too much for an ECG Blog, but suffice it to say that, s hortly thereafter, the patient had an asystolic arrest and was resuscitated. The initial K was 3.0 mEq/L and ionized calcium was 5.5

Figure B At this point, with the ECG changing from diffuse ST depression to widespread ST elevation and the patient presenting in cardiogenic shock, left main coronary artery (LMCA) occlusion is the likely diagnosis. And then, 15 minutes later in today's case — this patient was in cardiogenic shock.

The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). LAD — 100% proximal occlusion; with 70-89% mid-vessel narrowing.

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?

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. RVMI explains part of the shock. BP was 108 systolic (if a cuff pressure can be trusted) but appeared to be maintaining BP only by very high systemic vascular resistance.

The patient died of cardiogenic shock within 24 hours despite mechanical circulatory support. The axis is to the right and QRS complexes in lead I and aVL are predominantly negative suggesting LPFB. This patient at cath had a large CX occlusion with a massive troponin release. Troponin T >42.000ng/L.

My most talented blog readers are paramedics because they have to put themselves on the line every time they activate the cath lab. 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. And they teach me a lot. What was the diagnosis?
