“…This observation was consistent with an incidence of 19% previously reported by Vassallo et al However, it is important to note that this was a small population study in both series. Artifacts that may occur due to hypothermia in hypothermic patients may cause difficulties in diagnosing atrial fibrillation [ 16 - 18 ]. Vassallo's study found that a regularly occurring rhythm represents a sinus mechanism, compared to a rhythm with an irregular appearance despite an uninterpretable baseline based on ECG artifacts from patients with similar rhythms [ 19 ].…”

Hypothermia is an involuntary fall in body temperature, usually below 35°C. Hypothermia is a common condition, especially in frigid zones. However, it should not be forgotten that it can also occur in temperate climates or for iatrogenic reasons. Hypothermia is associated with seriously severe arrhythmias, particularly ventricular fibrillation, and there are many reports of prolonged resuscitation in these patient groups. This case report shows that a standard thermometer, either with Emergency Medical Services or in-hospital, will be incapable of reading the temperature if it is less than 34°C and will falsely read 34°C when in reality it is lower than that; in a clinically relevant scenario, a low-reading thermometer or core body temperature readings, such as rectal or esophageal, should be used.
