What ECG finding is commonly expected in a patient with hypothermia?

In cases of hypothermia, the presence of Osborne waves, also known as "J waves," is a characteristic and commonly recognized ECG finding. These waves appear as small, rounded deflections at the junction of the QRS complex and the T wave or in the terminal portion of the QRS complex. Osborne waves typically occur due to the altered myocardial depolarization and repolarization associated with decreased body temperature.

As the body cools, metabolic processes slow down, and alterations in ion channel function can manifest on the ECG. Osborne waves are particularly notable because they provide a visual marker that can alert clinicians to the presence of significant hypothermia, helping guide timely interventions.

Understanding these waves allows for prompt recognition of the complications arising from severe hypothermia, leading to appropriate medical response, including rewarming techniques and other supportive measures.
