J-wave syndromes: Brugada and early repolarization syndromes.
A prominent J wave is encountered in a number of life-threatening cardiac arrhythmia syndromes, including the Brugada syndrome and early repolarization syndromes. Brugada syndrome and early repolarization syndromes differ with respect to the magnitude and lead location of abnormal J waves and are thought to represent a continuous spectrum of phenotypic expression termed J-wave syndromes. Despit...
متن کاملJ Wave Syndromes: A Decade of Progress
OBJECTIVE The objective was to provide a brief history of J wave syndromes and to summarize our current understanding of their molecular, ionic, cellular mechanisms, and clinical features. We will also discuss the existing debates and further direction in basic and clinical research for J wave syndromes. DATA SOURCES The publications on key words of "J wave syndromes", "early repolarization s...
متن کاملJ-wave syndromes. from cell to bedside.
The J wave, a deflection that follows the QRS complex of the surface electrocardiogram, is usually partially buried in the R wave in humans, appearing as a J-point elevation. An early repolarization (ER) pattern characterized by J-point elevation, slurring of the terminal part of the QRS, and ST-segment elevation has long been recognized and considered to be totally benign. Recent studies have ...
متن کاملJ Wave Syndromes: History and Current Controversies
The concept of J wave syndromes was first proposed in 2004 by Yan et al for a spectrum of electrocardiographic (ECG) manifestations of prominent J waves that are associated with a potential to predispose affected individuals to ventricular fibrillation (VF). Although the concept of J wave syndromes is widely used and accepted, there has been tremendous debate over the definition of J wave, its ...
متن کاملRationale for the use of the terms J-wave syndromes and early repolarization.
q a t r e c i F ( d g a e d a t f s f a t d t m The J-wave is a deflection immediately following the QRS complex of the surface electrocardiogram (ECG) that has been linked to the development of a pronounced dispersion of repolarization within the ventricular myocardium leading to the development of cardiac arrhythmias. When partially buried in the R-wave, the J-wave appears as a J-point elevat...
