Case of Recurrent Ventricular Fibrillations with Osborn Wave Developed during Therapeutic Hypothermia

摘要

Therapeutic hypothermia (TH) has been used to protect neurological functions in cardiac arrest patient. Although Osborn wave is not pathognomonic of hypothermia, it is a well-known electrocardiogram finding of hypothermic patients. The cellular and ionic mechanisms of the Osborn wave have been suggested, and its relationship to tachyarrhythmias, such as ventricular tachycardia and ventricular fibrillation, is being explored. This case highlights the arrhythmogenic potential of Osborn wave and individual difference in response of TH.
