A previously healthy 53 yo woman was transferred to a receiving hospital in cardiogenic shock. Here was the ECG: There is sinus tachycardia. Referring to Figure-1 — this 53-year old woman who presented in extremis with cardiogenic shock and an initial pH = 6.9, This was sent by a reader. and K was normal.

She presented to an outside hospital after several days of malaise and feeling unwell. Sinus tachycardia has many potential causes. This is especially true for the elderly patient with sinus tachycardia. What is the cause of the sudden tachycardia? The VSR is what is causing the cardiogenic shock!

Author continued : STE in aVR is often due to left main coronary artery obstruction (OR 4.72), and is associated with in-hospital cardiovascular mortality (OR 5.58). Authors' commentary: Cardiogenic shock in the setting of severe aortic stenosis. Fundamentally, cardiogenic shock is an issue of decreased cardiac output.

The patient had a protracted hospitalization and did not survive. There is sinus tachycardia at ~100/minute. As often emphasized by Dr. Smith — sinus tachycardia is not a common finding with acute OMI unless something else is going on (ie, cardiogenic shock ). The initial ECG for Patient #2 also shows RBBB.

Category 2 : An increase in myocardial oxygen demand due to tachycardia, elevated ventricular afterload (BP or aortic stenosis), or increased wall stretch (admittedly this latter is more complicated) or a decrease in oxygen supply due to hypotension, anemia, hypoxia, or a combination of all of the above. This results in Type I MI.

An elderly man with sudden cardiogenic shock, diffuse ST depressions, and STE in aVR Literature 1. However, STE-aVR with multilead ST depression was associated with 31% in-hospital mortality compared with only 6.2% A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ). Left main?

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. He was later transferred back to his local hospital neurologically intact and without serious sequela.
