Classic Osborn waves and incessant ventricular fibrillation in severe hypothermia.

Abstract

Cardiac arrhythmias in severe hypothermia are common and are managed primarily by re-warming techniques. A 64-year-old male presented with alcohol associated aspiration pneumonia, sepsis and severe hypothermia and was noted to have classic ECG changes of hypothermia, i.e. Osborn waves. The patient had a tumultuous clinical course with prolonged resuscitative measures. Ultimately, an early focus on invasive core temperature re-warming with cardio-pulmonary bypass resulted in a favorable outcome.
