      Citation Excerpt :

      The electrophysiopathologic mechanisms of this phenomenon are disturbances of the transmembrane polarity at the beginning of repolarization because of alterations in the cardiac transient outward potassium current (4). Specifically in hypothermia, there is an increase of intracellular calcium that affects the L-type calcium current that results in the appearance of this wave (5). Although the isolated finding of a J-wave in the ECG is not classified as part of the J-wave syndromes (which include Brugada syndrome and early repolarization syndrome), there are electrophysiopathologic similarities that could generate reentry or extrasystoles that could induce a “R-on-T” phenomenon as a possible substrate for the appearance of ventricular dysrhythmias (6).

      He described the J wave as a “current of injury” and postulated its occurrence was secondary to hypothermia-induced acidosis.16 The Osborn wave (also known as camel-hump sign, late delta wave, hathook junction, hypothermic wave or prominent J wave), is a positive deflection occurring at the junction between the QRS complex and the ST segment, where the S point (which is also known as the J point) has a myocardial infarction-like elevation.17–18 The mean vector axis of the J wave is oriented anteriorly, inferiorly and leftward across the left ventricle and septum.6,19
