Cold at the Core: Osborn Waves in Neurosarcoidosis-Induced Central Hypothermia

Figure 2

(a) Electrocardiogram at 32°C revealing sinus bradycardia with premature atrial contractions, Osborn waves most prominent in the precordial lateral leads, prolonged PR and QT intervals. (b) Electrocardiogram after initiation of treatment reveals an increase in heart rate to 60 beats per minute and an improvement of the PR (210 ms), QRS (98 ms), and QT (QTc 432 ms) intervals.
