Key result
Hypothermia is linked to classic J waves, interval prolongation, and patterns mimicking acute ischemia or Brugada syndrome.
Why the study?
Hypothermia is associated with a variety of ECG abnormalities, including less well defined signs that may mimic other cardiac conditions, requiring detailed understanding for accurate diagnosis.
ECG mimics of ischemia or Brugada in hypothermia warrant diagnostic caution; review extends known findings but leaves validation open.
Hypothermia is a common environmental emergency encountered by physicians and is associated with a variety of electrocardiographic (ECG) abnormalities. The classic and well-known ECG manifestations of hypothermia include the presence of J (Osborn) waves, interval (PR, QRS, QT) prolongation, and atrial and ventricular arrhythmias. There are less well defined and known ECG signs of hypothermia, which in fact may simulate findings of acute coronary ischemia, Brugada syndrome, or even pericarditis. Although classical ECG changes seen in hypothermia certainly serve as an important clinical clue for prompt identification and management of this easily curable life-threatening entity, physicians should, however, be able to maintain a high suspicion for recognition and differentiation of less common ECG abnormalities encountered in hypothermia. This article aims to provide a detailed review of all the potential ECG abnormalities that may be encountered in accidental and iatrogenic hypothermia.

Chhabra et al. (2013) conducted a review in Hypothermia. Hypothermia was evaluated on Electrocardiographic (ECG) abnormalities. Hypothermia is associated with classic ECG manifestations like J waves and interval prolongation, as well as less common signs that may simulate acute coronary ischemia or Brugada syndrome.
