New data from S. Rituparna et al illuminate research in acute ischemia
2007 SEP 10 -- "The ''J wave'' (also referred to as ''the Osborn wave,'' ''the J deflection,'' or ''the camel's hump'') is a distinctive deflection occurring at the QRS-ST junction. In 1953, Dr. John Osborn described the ''J wave'' as an ''injury current'' resulting in ventricular fibrillation during experimental hypothermia," scientists in Pune, India report. "Although ''J Wave''' is supposed to be pathognomonic of hypothermia, it is seen in a host of other conditions such as hypercalcemia, brain injury, subarachnoid hemorrhage, cardiopulmonary arrest from over sedation, the Brugada syndrome, vasospastic angina, and idiopathic ventricular fibrillation. However, there is paucity of literature data as regards to ischemic etiology of ''J Wave.'' In this article, we present a case where ''J waves'' were probably induced by ischemia," wrote S. Rituparna and colleagues. The researchers concluded: "We also discuss the mechanism of ischemia-induced ''J wave'' accentuation and its prognostic implications." Rituparna and colleagues published their study in Pace - Pacing and Clinical Electrophysiology (Occurrence of ''J waves'' in 12-lead ECG as a marker of acute ischemia and their cellular basis. Pace - Pacing and Clinical Electrophysiology, 2007;30(6):817-819). For additional information, contact S.
