STEMI Mimics and STEMI Equivalents

Here’s my presentation from the VA EMS Symposium on 11/08/2013. STEMI Equivalents and STEMI Mimics from Tom Bouthillet

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 […]

41 year old male CC: Chest pain – Answer

Entry Img

Thank you for all of the excellent comments on this case! I was delighted to see such a high level dialog when I checked my blog this morning. Normally I would to answer each of you individually, but since there are 22 comments (so far) I thought I would try a different strategy and post the […]

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 […]

The Trouble with Sinus Tachycardia
It has been very insightful for me as i read this post. Thanks to the may people who commented. Like many nurses, I was also taught to differentiate svt from st by rate and now I stand corrected. I have a Telemetry test coming up soon, I wont have the patient in front of me…

100 yof CC: Rib pain and intermittent spasms
Can't be a potassium imbalance. The TW's wouldn't change and then change back. If it was coronary spasm, I would expect some ST segment elevation. The TW'S are also not hyperacute (peaked). Does she wear some sort of electronic stimulator?

Not just S1Q3T3: Look at the other 10 leads!
[…] Last week, I described the case of a middle-aged male with a vague history of heart failure who had been having progressive shortness of breath for 4-5 days. On the day he called 911, he had been walking a short distance when he syncoped. EMS obtained an ECG: […]

I believe this may be coronary artery vasospasm.

What it Looks Like: Cardiac Arrest
this is really interesting because something similar happened to a patient as I sat them up in bed after delivering them to a community hospital in fact I even turned to his son and said "does dad suffer with epilepsy?" And then turned back and realised he wasn't breathing
