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!

At a quick glance it looks like tombstones (R on T). At closer look without calipers, it appears to be accelerated ideoventricular rhythm due to complete heart block. Not enough information to go off of, so cardioverting or pacing might just kill the patient quicker than anything. Transport immediately since his sick heart could stop…

I've only studied cardiology for a few months and have read Dubin's book 1.5 times so I'm not an expert by any means. However, can a possible interpretation be a junctional tachycardia with aberrant ventricular conduction and a STEMI? No P waves and aberrancy causing a slightly wide QRS (but not wide enough for V-Tach).

This is a ugly EKG. Wide complex irregular tachycardia around 150's. A-fib and a-flutter are possibilities. He's severely symptomatic. At this point, all treatment is same, electricity. If A fib, it may not want to "shock out" easily. This may be a case where initial cardioversion at max joules would be prudent. Pulmonary edema likely…

Calcium has little to no side effects, given the first EKG I think it is reasonable to consider it for first line treatment. Repeat EKG after 5 mins and reassess.

The Trouble with Sinus Tachycardia
An absolute must read for all Medics. Great article. I am always trying to tell students to consider referring to these fast rhythms as a narrow complex tachycardia, then start looking for the cause, be it physiologic response or an electrical conduction issue. And as many have stated, I often hear that it must be…
