WebNov 22, 2024 · J point changes are the most important sign of early repolarization pattern, the diagnosis can be made even without ST-segment elevation. J Wave The J wave, also known as Osborn wave, is a deflection with a dome or hump morphology in the same direction as the R wave, immediately following the QRS complex 6 . WebJun 8, 2024 · The J point and ST-segment elevation which sometimes manifests as a notch or slur of the QRS (J wave) is the characteristic ECG pattern of early repolarization (ER). Moreover, recent studies have demonstrated that J wave on the sECG is associated with ventricular tachycardia (VT) and fibrillation (VF) in an experimental model consisting of ...

WebApr 7, 2024 · The J (junction) point in the ECG is the point where the QRS complex joins the ST segment. It represents the approximate end of depolarization and the beginning of repolarization as determined by the surface ECG.

WebFigure 1. Exercise causes subendocardial ischemia and thus ST segment depression on the ECG. Measuring ST depression: J point, J 60 point & J 80 point. ST segment depression is measured anywhere between the J-60 point and J-80 point. The J-60 point and J-80 point are located 60 ms and 80 ms, respectively, after the J point (Figure 2). As usual ... WebNov 15, 2011 · Early repolarization pattern (ERP) is a common ECG variant, characterized by J point elevation manifested either as terminal QRS slurring (the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal QRS complex) associated with concave upward ST-segment elevation and prominent T waves …
