Jan 1, 2022 · The Osborn wave (J wave) is a positive deflection seen at the J point in precordial and true limb leads. It is most commonly associated with hypothermia. These changes will appear as a reciprocal, negative deflection in aVR and V1.

In this paper, we present a historic review of Osborn waves and discuss their clinical significance in the various clinical settings. Figure 1. Twelve-lead ECG obtained in a 56-year-old man with a core body temperature of 32.7º C because of accidental exposure to cold.

The J wave – also referred to as Osborn’s wave – is defined as a wave occurring at the J point (Figure 1). Conditions in which the J wave occurs may be referred to as J wave syndromes. J waves are typically most pronounced in the anterolateral (V3, …

Osborn waves, also known as J waves, camel-hump waves, and hypothermic waves, are best seen the inferior and lateral precordial leads. They become more prominent as the body temperature drops, and they regress gradually with rewarming.

The J wave is a normal variant in young athletes, without structural heart disease. After correcting hypothermia, the Osborn wave may persist for 12-24 hours. Explore the J wave mechanism, causes of the Osborn wave, and its appearance in ECGs. Understand the dynamics of the Osborn wave in hypothermia.

The electrocardiographic J wave, also referred as the Osborn wave, is a deflection with a dome or hump morphology at the junction between the QRS complex and the ST segment on the body surface ECG.

Oct 28, 2024 · Osborn Waves. The Osborn wave (J wave) is a positive deflection at the J point (negative in aVR and V1). It is usually most prominent in the precordial leads. The height of the Osborn wave is roughly proportional to the degree of hypothermia

Aug 14, 2015 · The Osborn wave is a deflection with a dome-shaped configuration at the R-ST junction of the electrocardiogram. It is mainly encountered in hypothermic states but is also recognized in other nonhypothermic conditions. It has important prognostic implications that warrant its recognition by various health-care providers.

J waves, also known as Osborn waves or the camel-hump sign, can be caused by hypercalcemia, brain injury, subarachnoid hemorrhage, and cardiopulmonary arrest from oversedation, vasospastic angina, or ventricular fibrillation. 1 However, the chief cause is hypothermia (body temperature, <90 °F).

The Osborn wave is a deflection with a dome-shaped configuration at the R-ST junction of the electrocardiogram. It is mainly encountered in hypothermic states but is also recognized in other nonhypothermic conditions.
