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



  • 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


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


  • 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.
I would do a v4r to see if right side involvement as well as posterior v8-v9. Based on the pt not presenting hypotensive this can be RCA occlusion caused by disection of thoracic aortic aneurysm! Debakey type 1 aneurysm! No catch lab however surgical intervention would be required!

It's most likely a RVMI because the ischemia/infarction has effected the SA node. IWMI with bradycardia should highly suspect a RVMI. Not all RVMI's are preload dependant. Do a 15 lead ecg to verify V4R elevation. Have 2 IV's established with a bolus of at least 1L of fluid before giving nitrates. If the pt…

I kept feading this thread to see how long it'd take for someone to call it as it is 'inferioposterior MI' and the prize goes to iliyas on Sept 11.

S-T (J-Point) elevation in II, III, and AVF are clear. There are no repol abnormalities. There are even reciprocal changes. IV with fluids is a must but beyond that, what else is there. Females, especially, present with atypical symptomologies. Be ready with fluids, but treat with standard AMI protocols. Presentation, ECG, age, sex, it's not…

“You Make the Call” — 86 Year old Female: Dizzy
There is no LBBB as QRS <120ms. Diagnosing LAHB in a patient with LVH is difficult. ST elevation is appropriate for LVH. 1st degree HB rarely causes symptoms, but when combined with a betablocker could be problematic. I'd want her to have 24 hours telemetry monitoring to rule out cardiac causes of dizziness.
