Normally, ventricular response is slow in atrial dysrhythmias. They should not be treated since they are innocent. During rewarming, preexisting ventricular ectopy could reappear and throw the picture off. Treatment for ventricular dysrhythmia is challenging since the cold heart may not respond to cardiovascular medications. Only one defibrillation effort (2 J/kg) is advised if the patient is in ventricular fibrillation until the core temperature reaches 30°C to 32°C. With movement, endotracheal intubation, and the insertion of a jugular or subclavian catheter, patients who are moderately or severely hypothermic are at a significant risk of decompensating into cardiac dysrhythmia.
