ECG ANSWER and INTERPRETATION
This ECG demonstrates classic features of hypothermia:
- Osborn waves (J waves) = notching at the J point seen in V2-6
- Long QT interval (~ 600 ms)
- Shivering artifact
The rhythm is probably sinus bradycardia — mapping out the RR intervals reveals a regular rhythm despite the obliteration of the baseline by the shiver artifact.
