Hypothermia can cause J waves, or Osborn waves, bradycardia, a prolonged QT, and motion artifact from shivering.

Hypothermia
Osborn waves can mimic ST-segment elevation as was the case with this post-arrest ECG. Slow atrial fibrillation is another hallmark of hypothermia. The core temperature was 76 deg F (24.4 deg C).References
