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

Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). ECG 2 Especially in the context of the first ECG, readers of this blog will readily appreciate the ST elevations and hyperacute T waves in II, III, aVF, V6, and to a lesser extent V5. link] I also texted the ECG to Dr. Smith.

With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. An elderly man with sudden cardiogenic shock, diffuse ST depressions, and STE in aVR Literature 1. See this case: what do you think the echocardiogram shows in this case? Left main? 3-vessel disease?

Some patients have baseline RBBB with LAFB, but in patients with likely ACS, these are associated with severe infarction with cardiac arrest, cardiogenic shock or impending shock. Today's patient did make it to the hospital — but was in cardiogenic shock, and despite valiant attempt at treatment, succumbed soon after.

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. However we also noticed that the rhythm is rapid, regular, and narrow, with no P-waves, at a rate of approximately 200 bpm, and therefore not sinus rhythm in this patient in his 60s.

Because of the tachcardia, I would expect her to be very poor left ventricular function and maybe Cardiogenic shock. As per Dr. Smith — this suggests that despite QRS widening, the rhythm in ECG #3 is AFib with a rapid ventricular response. Old MI with persistent ST Elevation (LV aneurysm morphology) can look like acute MI 2.
