Various electrophysiological changes are known to be caused by hypothermia. The hypothermic ECG, below 31°C, is characterized by bradycardia, prolongation of the QT and PQ intervals, widening of the QRS complex and above all by a slowly inscribed deflection ware, called the J wave, located between the end of the QRS complex and the beginning of the ST segment. There is a significant relationship regarding the appearance of the J wave and the onset of subsequent ventricular fibrillation, although the genesis of this obscure J wave is still not completely understood.
