Low voltage is defined as peak-to-peak QRS amplitude of < 5 mm in the limb leads and/or < 10 mm in the precordial leads. Note: If the gain indicated at the left of the ECG is turned down ...

Some other ECG findings in hypothermia include low voltage, bradycardia (can be junctional, atrial fibrillation or higher grade AV blocks as in this ECG), artifact from shivering and non-specific ...
