STEMI Mimics and STEMI Equivalents

Here’s my presentation from the VA EMS Symposium on 11/08/2013. (This content is no longer available.) See our comprehensive video-based 12-lead ECG course at ECG Medical Training.

The early repolarization experiment

Entry Img

Any paramedic who has studied the STEMI mimics has heard of the classic benign early repolarization pattern of a "fish-hooked" J-point with upwardly concave (smiley-faced) ST-segment, often best appreciated in lead V4. But, as the excellent work of Stephen Smith, M.D. demonstrates, not all cases of early repolarization present this way, and it can often […]

Discussion for 51 Year Old Male: Chest Pain

Entry Img

Here is the conclusion to 51 year old male: Chest Pain. You may wish to review the case. Here is the ECG again:   There is a regular sinus rhythm at a rate of about 70. The QRS is narrow. The axis is normal, at about 15 degrees. Let's take a look at the constellation […]

Elderly Female: Chest Pain-Discussion

Entry Img

This is the discussion for Elderly Female: Chest Pain. You may wish to review the case. Ok, this was not an obvious case, at least, not until the end.  As far as the patient goes, I think we all agree about the differentials: ACS vs. possible aortic dissection (due to the pain radiating to her […]

47 year old female CC: Chest pain – Discussion

Entry Img

Thanks for all the comments! I’m not allowed to blog while I’m on duty (the policy has nothing to do with me personally) so if it seems like I’m not responding, I’m probably just at work. The paramedic who submitted this case has requested the follow-up information from his supervisor, but unfortunately she’s out-of-town for […]

PowerPoint Presentation on Strain Patterns!

This is an awesome PowerPoint presentation from one of my favorite ECG textbooks, 12-Lead ECG – The Art of Interpretation. You owe it to yourself to purchase this book (and no, they don’t pay me to say that). Make sure you use “full screen” so you can see all of the features of this important […]

Left ventricular hypertrophy – Part II

Entry Img

I know I promised to go over the voltage criteria for left ventricular hypertrophy (LVH) but I lied! If you’re really interested you can check out the Wikipedia article HERE, the ECG Learning Center HERE, or Tom Evans’ crib sheet HERE. Personally? I think it’s a distraction. As far as STEMI recognition goes, it misses […]

Discordant ST-Segment Elevation in LBBB or Paced Rhythm

Entry Img

If you’ve been following the Prehospital 12-Lead ECG blog for a while, you know that I’m advocate of using Sgarbossa’s criteria to help identify acute STEMI in the presence of left bundle branch block (LBBB) or paced rhythm. According the Sgarbossa’s original criteria, 5 mm of discordant ST-segment elevation is required to identify AMI in […]

Wolff-Parkinson-White (WPW) – STEMI Mimic

Entry Img

A really interesting 12-Lead ECG was posted to the Cardiology & Electrocardiography (ECG, EKG) Experts group on Facebook the other day. If you’re not familiar, this is one of the groups / fan pages on Facebook I help moderate with Jason Winter who also started the Cardiology & Electrocardiography Experts blog. What’s so interesting about […]

"New" LBBB – What's the big deal?

In the January 2010 EMCast at EMedHome.com, Amal Mattu MD reviews Chang AM, Shofer FS, Tabas JA, et al. Lack of association between left bundle-branch block and acute myocardial infarction in symptomatic ED patients. Am J Emerg Med 2009;27:916-921. His comments confirm what I have suspected for a long time with regard to LBBB in […]
