[Electrocardiographic finding of Osborn's J wave in patients with hypothermia. Description of 2 clinical cases].

Two cases of hypothermia in the elderly are described. The different clinical evolution shows how the concurrent presence of Diabetes Mellitus can be considered as an adverse prognostic factor. It is also confirmed that the Osborn's wave electrocardiographic presence, given up a specific and pathognomonic diagnostic parameter in this disease. The observation that the electrocardiographic J wave can regress after body's temperature normalization suggests the hypothesis that this wave reflects reversible delay of depolarization, or early repolarization.
