Osborn waves of hypothermia.

A12-lead ECG was obtained from a 72-year-old man with a core body temperature of 85°F (Figure 1). The ECG shows severe sinus bradycardia with prolonged PR, prolonged QRS complex, prolonged QT interval, and an extra deflection at the end of the QRS complex (Osborn waves) (arrows). A second 12-lead ECG obtained 24 hours later, after the patient had been rewarmed to 98°F, was normal (Figure 2). Hy...

Osborn Waves: History and Significance

The Osborn wave is a deflection with a dome or hump configuration occurring at the RST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign”, “late delta wave”, “hathook junction”, “hypothermic wave”, “J point wave”, “K wave”, “H wave” and “current of injury”.1 Although there is no defini...

A hypothermic case with giant Osborn waves and atrial fibrillation after using synthetic cannabinoid

Hypothermia is a condition wherein the body temperature drops below 35°C when an individual is unconscious. In prolonged moderate hypothermia (28–32°C), progressive drops in the pulse rate and increases in atrial and ventricular arrhythmia and Osborn waves are observed in electrocardiography (ECG). Unconsciously, staying outside for an extended time in extreme cold is the most important cause o...
