Özet

The Osborn (J) wave refers to a dome-shaped deflection on the electrocardiogram, that appears as a late delta wave following the QRS complex or as a small secondary R wave (R'). A 25-year-old man was found unconscious in the open in cold and snowy weather. Electrocardiogram obtained on admission showed atrial fibrillation with a normal ventricular rate, increased duration of the QRS complex and the QT interval, and the J wave in all derivations. Rectal temperature was measured as 27.1 degrees C. In addition, cranial tomography showed subdural hematoma in the left parietal region. Treatment for subdural hematoma and hypothermia resulted in normal sinus rhythm and disappearance of the J wave on the electrocardiogram obtained in the 24th hour. However, he developed brain death due to deterioration in the intracerebral pathology at 30 hours.
