A woman in her 70s with bradycardia and hypotension

Dr. Smith's ECG Blog

There is STE in III and aVF which does not meet STEMI criteria due to insufficient STE in lead aVF. Resuscitation was initiated and this ECG was obtained: Likely AFib (irregularly irregular) with bradycardia. The cardiologists were not familiar with this and insisted that the ECG in paced rhythm could not be used to "look for a STEMI".

Serial ECGs for chest pain: at what point would you activate the cath lab?

Dr. Smith's ECG Blog

There’s competing sinus bradycardia and junctional rhythm, with otherwise normal conduction, borderline right axis, normal R wave progression and voltages. While STEMI negative, the ECG is diagnostic of proximal LAD occlusion. Transient STEMI” are often managed like non-STEMI with delayed angiography, which is very risky.

Unconscious + STEMI criteria: activate the cath lab?

Dr. Smith's ECG Blog

ECG met STEMI criteria and was labeled STEMI by computer interpretation. This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern.

ECG #413 — A Pre-Op ECG in an ASx Patient

Ken Grauer, MD

Looking first at the long-lead II rhythm strip — there is significant bradycardia , with a heart R ate just under 40/minute. But the point to emphasize — is that it should only take seconds to recognize that there is bradycardia from significant AV block. = Would you approve her for a nonemergent surgical procedure?

A 50-something with chest pain. Is there OMI? And what is the rhythm?

Dr. Smith's ECG Blog

I will leave more detailed rhythm discussion to the illustrious Dr. Ken Grauer below, but this use of calipers shows that the rhythm interpretation is: Sinus bradycardia with a competing (most likely junctional) rhythm. For national registry purposes, this will be incorrectly classified as a STEMI.) Large STEMI are approximately 30-80.

ECG Blog #392 — Repolarization T Waves?

Ken Grauer, MD

I see the following: The rhythm is sinus bradycardia at ~55-60/minute. These tall T waves are associated with flattening ( straightening ) of the ST segment in the inferior leads — with slight S T elevation in leads V2-thru-V6 ( albeit not enough to qualify as a "STEMI" — Akbar et al, StatPearls, 2023 ).

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. There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). With longterm use there may be — bradycardia, AV conduction defects and risk of Torsades de Pointes ( especially in patients also on Digoxin ).
