Which ECG finding is associated with hypothermia?

Explanation:
Hypothermia alters ventricular repolarization enough to produce a distinctive J-point deflection called an Osborn wave. This wave appears as an extra upward notch at the end of the QRS, best seen in the chest leads as temperature drops. Osborn waves are the signature ECG sign of hypothermia, helping distinguish it from other conditions. U waves are usually due to hypokalemia or bradycardia, delta waves point to WPW pre-excitation, and those effects aren’t specifically tied to hypothermia.
