J wave

Cardiology A quasi-pathognomonic EKG change seen in13 of Pts with hypothermia, as a positive 'hump' at the end of a QRS complex, which disappears on rewarming Pt, bradyarrhythmia, atrial flutter, A Fib EKG Prolonged P-R and S-T intervals and T-wave inversion.

J wave

An upwardly curving deflection of the J point of the electrocardiogram, found in patients whose body temperature is less than 32°C. This finding is one cardiac effect of hypothermia. The J wave has a particular shape; viewed from above, its surface is convex. Synonym: Osborne wave

4) reported three patterns of repolarization as the ECG criteria for Brugada syndrome: a coved-type ST-segment elevation of [greater than or equal to] 2 mm (Type 1); saddle-back type with J-wave amplitude [greater than or equal to] 2 mm giving rise to a gradually descending ST elevation remaining [greater than or equal to] 1 mm above baseline (Type 2); and coved-type or saddle-back type ST elevation of [less than or equal to] 2 mm (Type 3).
