2022年1月1日 · 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. The J point in the ECG is the point where the QRS complex joins the ST segment.

The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG . 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 ...

2024年10月28日 · 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

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, …

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.

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 .

1996年1月15日 · The presence of a prominent action potential notch in epicardium but not endocardium is shown to provide a voltage gradient that manifests as a J (Osborn) wave or elevated J-point at the R-ST junction of the ECG.

In 1953, Joseph Osborn examined the physiologic effects of hypothermia and defined typical associated changes in the electrocardiogram (ECG), now known as J waves of Osborn. There is a subtlety, however: Osborn's J waves were absent in hypothermic animals whose pH was maintained via mechanical ventilation.

2000年6月27日 · At this level of hypothermia, 80% of patients have Osborn waves that consist of an extra deflection at the end of the QRS complex. Osborn waves, also known as J waves, camel-hump waves, and hypothermic waves, are best seen the inferior and lateral precordial leads.

2017年10月1日 · On 12-lead electrocardiography, elevation of the J point (Osborn wave; arrows) is typically seen in precordial leads V 3 to V 6 and is a marker for hypothermia. The amplitude of Osborn waves is directly proportional to the degree of hypothermia.
