Kim CY, Bae MH, Kim NK, Yang YA, Kim KY, Lee JH, Eun JS, Cho Y - Korean Circ J (2015)

Bottom Line: Therapeutic hypothermia (TH) has been used to protect neurological functions in cardiac arrest patient.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.

ABSTRACT
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.

Figure 1: Initial electrocardiogram recorded by automated external defibrillator shows ventricular tachycardia.

Mentions: A 56-year-old man with no underlying disease was admitted to the emergency department with sudden cardiac arrest. While having breakfast, he suddenly pounded his chest. His wife noticed he was cyanotic and having difficulty breathing. He received cardiopulmonary resuscitation (CPR) from his son for about 20 minutes until paramedics arrived with a defibrillator. The initial rhythm was VF (Fig. 1). Defibrillation with 200 J was delivered once followed by 5 cycles of CPR. Following restoration of cardiac rhythm, he was transferred to a hospital where he was intubated. The initial ECG finding was sinus tachycardia. He was transferred to our hospital for further management.
