A 41-year-old man with a known history of ethanol abuse is brought to the emergency department after being found on the street by EMS workers. Upon presentation, the patient's eyes are closed, he is moaning, and does not follow commands. Below is his ECG.
2. Name 3 conditions that can lead to this patient's diagnosis?
3. True or False -- Atropine should be used to increase the heart rate?
1. Hypothermia (ECG represents Osborn or J waves, which occur in cases of severe hypothermia. It presents as a large deflection at the end of the QRS complex. The cause of the wave is not known. The colder the patient's core temperature, the higher the Osborn wave)
2. a) low temperature exposure b) sepsis c) Addison's disease d) hypothyroid e) those that Aaron listed
3. False - the hypothermic heart is insensitive to atropine. Warming techniques are the best way to increase the heart rate
The next VizD will be posted on Monday March 5
