• In hypothermia, ECG findings may include:
Sinus bradycardia
AV block
Osborn waves ("camel-hump" wave, prominent J wave)
• There is an increased risk of cardiac arrest such as PEA (pulseless electrical activity) and asystole (as bradyarrhythmia progresses) as well as fatal tachyarrhythmia (especially during rewarming) when ventricular ectopic beats kick in.
