Osborn waves in normothermic patient with hydropneumothorax and myocardial ischemia

Osborn waves in a hypothermic patient

A 56-year-old man presented with hypothermia (rectal temperature of 30.18C) and hypotension after being found by emergency medical services (EMS) on his basement floor. A 12-lead electrocardiogram (ECG) revealed normal sinus rhythm with a rate of 62 bpm, right bundle branch block, prolonged QT interval (QTc of 564 ms), wide QRS (110 ms), and a prominent J wave in the precordial leads (Fig. 1). ...

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...
