Conclusion to 68 yof CC: Unresponsive on kitchen floor – Osborn waves of hypothermia

Here is the conclusion to 68 year old female unresponsive on kitchen floor.

Let’s take another look at the 12-lead ECG.

This ECG is classic for severe hypothermia.

  • The rhythm is atrial fibrillation
  • It’s bradycardic
  • The QT/QTc is prolonged
  • Osborn waves (J-waves) are present throughout

You can see how the Osborn waves (J-waves) can be a STEMI mimic, which is one of the reasons we need clinical correlation with any ECG.

The patient was transported to the hospital where the core temperature was measured at 76°F (24°C).

The patient went into cardiac arrest and was defibrillated x3.

CPR was continued for the next 2 hours as the patient was re-warmed.

Remember, in this particular special resuscitation situation “you’re not dead until you’re warm and dead.”

The patient was not successfully resuscitated.

To see how Osborn waves can regress during rewarming, see Giant Osborn Waves in Hypothermia (Images in Clinical Medicine Case in the New England Journal of Medicine).

47 year old male CC: Crushing chest pain
I know this is old, but it just popped up on facebook so I'll go ahead and put in my $0.02 worth. With that hx and that 12-lead, there's no question this is an acute STEMI. I'm comfortable calling that third strip Torsades (assuming I've verified it's not an equipment issue). The defib pads are…

Adenosine for sinus tachycardia: Try to avoid this!
I have a better answer for Shay's patient (and Mel) and it's called lone a-flutter because I just had it diagnosed in me. I'm looking at my ekg showing a rate of 230 which fooled the doc who thought it was svt's until I told him I had no history of anything and talked him…
