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).

12 Lead ECG – Lead Placement Diagrams
I have been doing EKG's for the past thirty years. It use to be that you always lay the patient in the supine position but here lately I have been told that with the patient sitting up right will not change the EKG, is this so ?

Understanding Atropine
Hi Tony, thank you for writing. It's always a bit of a gamble to give opinion in such topics without being there, however, addressing ventilation is a must. The rate could be secondary to vagal stimulation and/or respiratory depression, but it sounds like the patient is compensating pretty well when it comes to the hemodynamic…

Understanding Atropine
Looking for an opinion. Had a pt. who was unconscious from unknown etiology, Agonal respiration = 6, SPO2 = 59, heart rate =37 sinus bradycardia, B/P = 137/80 . We ventilate the pt. approx for 2 minutes without change in status. Would you have administered atropine or continue with BVM to attempt to correct hypoxia,…

57 year old male: Chest Discomfort
I'm sorry but I don't see any flutter here. With a rate of 150 we are at the very upper limit of sinus tach. No O2 is indicated with a pulse ox of 94%, especially if you are thinking cardiac. Place in position of comfort, large bore IV, fluid bolus, ASA, nitro, capnography, complete assessment…
