Tachycardia must make you doubt an ACS or STEMI diagnosis; put it all in clinical context

Dr. Smith's ECG Blog

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. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock.

Acute artery occlusion -- which one?

Dr. Smith's ECG Blog

The conventional machine algorithm interpreted this ECG as STEMI. Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). Answer : Bedside ultrasound! Smith : RV infarct may also have this appearance on ultrasound.

Subacute AnteroSeptal STEMI, With Persistent ST elevation and Upright T-waves

Dr. Smith's ECG Blog

Thus, this is BOTH an anterior and inferior STEMI in the setting of RBBB. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. the presence of such well developed, wide, anterior Q-wave suggests completed transmural STEMI. Could it be acute (vs.

What are treatment options for this rhythm, when all else fails?

Dr. Smith's ECG Blog

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. The pain was 10/10 in intensity radiating bilaterally to the shoulders and also to the left arm and neck.

Two patients with chest pain and RBBB: do either have occlusion MI?

Dr. Smith's ECG Blog

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.

Diffuse Subendocardial Ischemia on the ECG. Left main? 3-vessel disease? No!

Dr. Smith's ECG Blog

Smith comment: This patient did not have a bedside ultrasound. Had one been done, it would have shown a feature that is apparent on this ultrasound (however, this patient's LV function would not be as good as in this clip): This is recorded with the LV on the right. In fact, bedside ultrasound might even find severe aortic stenosis.

Chest pain and shock: Is there a right ventricular OMI on this ECG? And should he undergo trancutaneous pacing?

Dr. Smith's ECG Blog

There is an obvious inferior posterior STEMI(+) OMI. Case continued A bedside ultrasound showed diminished LV EF and of course bradycardia. RVMI explains part of the shock. Results Of 149 patients with inferior STEMI , 43 (29%) had RVMI and 106 (71%) did not. What is the atrial activity? How would one tell?
