Cardiogenic Shock Stent Tachycardia

Past medical history includes coronary stenting 17 years prior. I find AV dissociation in VT to be very difficult to differentiate from artifact, as there are always random blips on tachycardia tracings. Read this post: Idiopathic Ventricular Tachycardias for the EM Physician 2. Initial ED ECG: What do you think?

The patient was referred immediately for cath which revealed RCA occlusion that was stented. The patient died of cardiogenic shock within 24 hours despite mechanical circulatory support. There is some down sloping ST-segment and T wave inversion in lead aVL. The findings are diagnostic of inferior and posterior wall OMI.

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. 2) Tachycardia to this degree can cause ST segment changes in several ways. Serial troponin T measurements rose from zero to 2.80 ng/mL over the next 10 hours.

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. He was successfully stented.

Here is another proven left main occlusion in a young woman who presented with sudden pulmonary edema, had this ECG recorded, then arrested and was resuscitated after 30 minutes of CPR: This has sinus tachycardia with RBBB and LAFB, and STE in V2-V6 as well as I, aVL This pattern could just as easily be seen in LAD occlusion.

The abnormal heart rhythms can further lead to death because of ventricular tachycardia and ventricular fibrillation. A completely blocked artery is located, a wire is inserted through it, the clot is sucked, the narrowing is widened with a balloon, and then a stent (stainless steel wire mesh) is placed to maintain consistent flow.

He had undergone stenting of the LAD several weeks ago (unclear whether elective for stable symptoms, or in response to acute coronary syndrome). It is a wide complex regular tachycardia at a rate of 120. Is it ventricular tachycardia? It is a wide complex regular tachycardia at a rate of 120. He appeared critically ill.
