Name that ECG: 66 year old female – Findings

This is the conclusion to our Name that ECG case: 66 year old female, resolved chest pain.

66 year old female, resolved chest pain.

Name that ECG: 66 year old female

 

Rhythm:

  • Rate: atrial rate of ~55 bpm, ventricular rate of ~55 bpm
  • Regularity: regular
  • P-waves: sinus (upright in I and II), associated 1:1 with the QRS
  • PRi: 140 ms
  • QRS duration: 90 ms

Bonus points:

  • Axis: -45 degrees, left axis deviation, LAFB
  • Bundle Branches: normal conduction
  • QTc: normal (<1/2 R-R interval), 420 ms (Bazett's Formula)
  • ST/T-waves:
    • T-waves: flipped T-waves in aVL, biphasic V2-V5 consistent with Wellen's Syndrome
    • ST-elevation: none noted
    • ST-depression: none noted

Differentials:

  • Normal sinus rhythm in a patient with Wellen's Syndrome
    • Possible high-grade stenosis of the LAD with recent reperfusion

Notes:

  • Wellen's Syndrome should be regarded with the same importance as a STEMI during assessment and transport.

    If you wanted to really push the limits of this ECG I also see inverted inverted U-waves in leads V2-V4, I, and aVL. They're super faint and I wasn't sure if I believed them at first, but measuring from the QRS to the U wave in III and aVF and transposing that interval to the other leads proves that it's really them.

    They don't add any information the T-waves don't tell you here, but heck, they're there.

    And now I'm really being a pain, but I think calling a LAFB is being a little generous to that LAD.  By my eye I put the axis, at most, at around -40 degrees. There's also no well developed rS complexes in II and aVF and the tracing lack the poor R-wave progression I usually see in true LAFB's. There doesn't seem to be an accepted criteria for making the Dx, but this one seems to be pushing it.

“Bad heartburn” – 82 y.o. female without chest pain.
The option was indeed turned on! As for non-CP presentations of ACS, I absolutely believe that these warrant the same level of urgency as the "typical" presentations. Both men and women, young and old, all commonly present without classic chest pain. Besides, how much difference is there between "burning in the epigastrium," and "pain in…

You took the words right off of my keyboard, Jason! A little bit of critical thinking works wonders when faced with "protocol versus best interests of the patient" type decisions. Not to encourage deviation from protocols and such, but it is a much less severe trespass if you bend the rules a bit as long…

My uninformed opinion? I pretty much agree with AHA - if they aren't hypoxic, no need. I'm not sure how terrible superoxia really is, short-term, but why bother if it doesn't help?

Chris Watford- as you probably know the "acute MI suspected" detection function in the LP12/15 is a programable option. I suspect the software didn't miss this but rather it wasn't turned on. As for treatment everyone has pretty much got it down. Finally as for activation. Absolutely! Don't real care if the protocol allows for…

There's not much I think I can add at this point, but I will comment on a couple of things. The reciprocal changes indicate to me that there is likely RCA involvement. Also, I've recently been hearing quite a bit about withholding O2 in ACS patients like this. Dr. Walsh, do you have any opinions…
