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. At first glance, it seems the patient is having a STEMI. Then ACS (STEMI) might be primary; this might be cardiogenic shock.

The conventional machine algorithm interpreted this ECG as STEMI. It shows sinus tachycardia with right bundle branch block. Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). Answer : Bedside ultrasound!

A male in his 40's who had been discharged 6 hours prior after stenting of an inferoposterior STEMI had sudden severe SOB at home 2 hours prior to calling 911. He had diffuse crackles on exam and B-lines on chest ultrasound, and chest x-ray also confirmed pulmonary edema. Here is his ED ECG: There is sinus tachycardia.

The prehospital and ED computer interpretation was inferior STEMI: There’s normal sinus rhythm, first degree AV block and RBBB, normal axis and normal voltages. The paramedic notes called STEMI into question: “EMS disagree with monitor for STEMI callout. Vitals were normal except for oxygen saturation of 94%. Vitals were normal.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. Here is that ECG: What do you think?
