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
