Discussion for 51 Year Old Male: Chest Pain

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 of ST changes:

There is ST elevation in leads I, aVL, V2-V6. There is slight ST depression in III and aVF (and arguably in lead II) with ugly looking T wave inversions. Some of you also noted the suspicious looking Q waves in III and aVF.

Pericarditis and Early Repol were put forth as possibilities. Remember though, that neither of those will have reciprocal changes (excepting myocarditis, which may present as STEMI). Here, we have reciprocal changes inferiorly. If you were inclined to be thinking about STEMI mimics in this case, those changes should put ischemia at the top of the list.  In addition, as some of you pointed out, the ST changes do not look like Early Repol, and the amount of ST elevation here is alarming.

The crew in this case, along with the physician, decided this was STEMI. The patient was given Heparin, ASA, anti-emetics, and Morphine. His condition improved enroute, and his BP climbed to 124/75.

Upon arrival at the hospital, he was taken directly to the cath lab. There was a complete blockage of the LAD.

 

Here is the cath lab image showing the blockage:

Here is the image after revascularization:

 

I don't know about you, but I always find these images amazing. Fortunately, our patient was discharged from the hospital to cardiac rehab a few days later. He was expected to recover nicely. 

Enjoy the holiday!

12 Lead ECG – Lead Placement Diagrams
I have been doing EKG's for the past thirty years. It use to be that you always lay the patient in the supine position but here lately I have been told that with the patient sitting up right will not change the EKG, is this so ?

Understanding Atropine
Hi Tony, thank you for writing. It's always a bit of a gamble to give opinion in such topics without being there, however, addressing ventilation is a must. The rate could be secondary to vagal stimulation and/or respiratory depression, but it sounds like the patient is compensating pretty well when it comes to the hemodynamic…

Understanding Atropine
Looking for an opinion. Had a pt. who was unconscious from unknown etiology, Agonal respiration = 6, SPO2 = 59, heart rate =37 sinus bradycardia, B/P = 137/80 . We ventilate the pt. approx for 2 minutes without change in status. Would you have administered atropine or continue with BVM to attempt to correct hypoxia,…

57 year old male: Chest Discomfort
I'm sorry but I don't see any flutter here. With a rate of 150 we are at the very upper limit of sinus tach. No O2 is indicated with a pulse ox of 94%, especially if you are thinking cardiac. Place in position of comfort, large bore IV, fluid bolus, ASA, nitro, capnography, complete assessment…
