He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. He had this ECG recorded.

Despite otherwise normal vital signs, she was appropriately triaged to the critical care area of the ED.

There is a regular wide complex tachycardia. I brought the patient to the critical care area and told the providers I thought it was atrial flutter with 2:1 AV conduction, but there is an outside chance that it is VT. Remember : Adenosine is safe in Regular Wide Complex Tachycardia. If it is VT, there will be no effect.

Although the shock is no doubt partly a result of poor pump function, with low stroke volume, especially of the RV, it should be compensated for by tachycardia. They did not have an ultrasound on the ambulance (some local crews are starting to utilize POC limited US in our service areas). This is a perfect indication for atropine.
