Abstract
The Osborn wave (also referred to as “the J wave,” “the J deflection,” or “the camel's hump”) is a distinctive deflection occurring at the QRS‐ST junction of approximately 80% of hypothermic patients (core body temperature ≤95°F). Generally, the amplitude and duration of Osborn waves are inversely related to core temperature. We report on eight normothermic patients whose 12‐lead electrocardiograms demonstrated QRS‐ST junction notches similar to those seen in hypothermia. These data support the concept that the Osborn wave is not pathognomonic of hypothermia.
