SpletAn early repolarization (ER) pattern characterized by J-point elevation, slurring of the terminal part of the QRS and ST-segment elevation has been traditionally consid-ered to be totally benign ... SpletA slurred R wave is known as a delta wave and a sign of ventricular activation through an extra pathway (WPW syndrome), and a possible cause of SVT. What you possibly mean is slurring of the S wave (downstroke on QRS complex). A slurred S wave can be a sign of so-called early repolarization, which actually often has nothing to do with ...

SpletJ wave. J waves, defined as an elevation of the QRS-ST junction ≥1 mm either as QRS slurring or notching, are a hyperacute sign of TTS with a prevalence of 16%–26% on the admission ECG ( Fig. 35.2D) [ 33, 34, 42 ]. The appearance of J waves in TTS was also associated with a lower LV ejection fraction and a higher CK-MB level and proved to ...

SpletWe aimed to describe the association of COVID-19 and T-wave inversion (TWI) in a large case series. Methods: We conducted an observational, retrospective study of confirmed COVID-19 cases with at least one electrocardiogram (ECG) in a large hospital in New York City (March 23, 2024-April 23, 2024). Patients with new TWI or pseudonormalization ... SpletNotch or slur in transition between R-wave and ST segment. ST-segment is virtually almost evident.
