Name that ECG: 66 year old female

Welcome to another installment of Name that ECG! Remember, this is a cold read and your job is to interpret the ECG to its fullest.

66 year old female, resolved chest pain.

Name that ECG: 66 year old female

 

Rhythm:

  • Rate?
  • Regularity?
  • P-waves?
  • PR interval? Associated?
  • QRS width?

Bonus points:

  • Axis?
  • QTc?
  • ST/T-wave changes?

What are your differentials?

    Interpretation: Sinus Brady @ 50-60 (based on upright P waves in I, II, III, avf and negative p wave in avr and hr < 60 w/ regular rhythm), Left Axis Deviation, LAFB(LAD, qr in I/AVL, rS in II, III, Avf), Biphasic T waves in V2, V3, V4 highly suggestive of Wellens Syndrome. Inverted T wave in AVL.
    Cheers!

    Wellen's Syndrome with some left axis deviation?

  • alex says:

     
    •Rate?
    About 60
     
    •Regularity?
    Regular
     
    •P-waves?
    Yes
     
    •PR interval? Associated?
    Borderline for 1st degree AVB. 1:1 association
     
    •QRS width?
    Normal at 0.08s
     
    •Axis?
    Left (positive QRS in I, negative QRS is aVF)
     
    •QTc?
    Less than half the RR interval so probably ok
     
    •ST/T-wave changes?
    Wellens waves in V2-V5
    TWI in I and aVL
     
    Which all points to partial LAD occlusion but isn't enough to activate a cath lab?

  • RyanTee says:

    Rate is about 60 bpm, regular rhythm P waves are these, PRI is good, QRS is wide with LBBB, LAD is seen..QTc is normal, Biphasic T waves seen with negative terminal – first stage of Wellens syndrome…urgent but not immediate cath…R waves are there meaning the artery is not yet infarcted…there is spontaneous reperfusion..

    I definitely say it’s textbook wellen’s syndrome. Inversion in AvL and hyper acute-ish looking T waves inferiorly kinda makes me think Type III wraparound LAD occlusion due to possible inferior injury with the more obvious anterior injury. Happy holidays kids!

  • @Ryan Tee – I'm not seeing any evidence of left bundle-branch block (LBBB).  In fact, if LBBB was actually present, then it would probably mask the ST-T changes of "Wellens' warning".  The duration of the QRS interval is normally narrow at 0.08s and there are triphasic "qRs" complexes in both lead I and V6.

    Rhythm: Sinus bradycardia
     
    Rate? 56
    Regularity? Yes.
    P-waves? Yes.
    PR interval? Associated? 0.16s. Yes.
    QRS width? 0.08s.
    Bonus points:
     
    Axis? QRS -30 degree. Z +40.
    QTc? 425 ms.
    ST/T-wave changes? Biphasic T-waves V1-V5. Retrograde in aVL.
    What are your differentials? LAD occulsion. I have nothing else to add to my DDx.
     
    =====================================================
     
    56, sinus bradycardia, LAFB, LAE, anteroseptal ischemia.
     
    Rate: 56
     
    Rhythm: Regular, p-waves present, P:QRS 1:1, PRi about 0.16s, QRS narrow 0.08s. Sinus bradycardia.
     
    Axis: QRS – I +, avF -, II -, -30 degree, LAD, LAFB (qR in I, rS in III too).
    Z V4 +40m, V1-V3 looks like the leads were placed 1 ICS too high (V3 r-wave >3 mm).
     
    Enlargement/Hypertrophy: Left atrial enlargement (2nd 1/2 of P-wave in V1 >0.04s, 1mm deep)
     
    ST/T, Q: insignificant q-waves in I and aVL. Significant Q in II and aVF. III has a small r-wave. No significant STE, but V1-V5 has retrograde T-waves. V2-V3, are those Wellen's T-waves? aVL also has a retrograde T-wave.
     
    QT 440 ms.
    QTc 425 ms.
     
    I'd be concerned about LAD occulusion cause of the T-waves in the anteroseptal leads.

Anterior T wave inversions and PE.
Studies (can't remember them off the top of my head) have shown that TWI in V1-4 + III is 85% likely to be RV strain, 15% ischemia. If I see anterior TWI, the very next lead I look to is III

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…

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.
