High Prevalence and Clinical Implication of Myocardial Bridging in Patients with Early Repolarization
PURPOSE Recent evidence suggests that early repolarization (ER) is related with myocardial ischemia. Compression of coronary artery by a myocardial bridging (MB) can be associated with clinical manifestations of myocardial ischemia. This study aimed to evaluate the associations of MB in patients with ER. MATERIALS AND METHODS In consecutive patients (n=1303, age, 61±12 years) who had undergon...
متن کاملEarly repolarization in an ambulatory clinical population.
BACKGROUND The significance of early repolarization, particularly regarding the morphology of the R-wave downslope, has come under question. METHODS AND RESULTS We evaluated 29 281 resting ambulatory ECGs from the VA Palo Alto Health Care System. With PR interval as the isoelectric line and amplitude criteria ≥0.1 mV, ST-segment elevation is defined at the end of the QRS, J wave as an upward ...
متن کاملA clinical approach to early repolarization.
T he term early repolarization (ER) is defined electrocar-diographically by either (1) a sharp well-defined positive deflection or notch immediately following a positive QRS complex at the onset of the ST-segment, or (2) slurring at the terminal part of the QRS complex (also termed J-waves or J-point elevation, Figure 1). Specifically, the ER pattern is present when J-point elevation of ≥0.1 mV...
متن کاملEarly Repolarization Syndrome; Mechanistic Theories and Clinical Correlates
The early repolarization (ER) pattern on the 12-lead electrocardiogram is characterized by J point elevation in the inferior and/or lateral leads. The ER pattern is associated with an increased risk of ventricular arrhythmias and sudden cardiac death (SCD). Based on studies in animal models and genetic studies, it has been proposed that J point elevation in ER is a manifestation of augmented di...
متن کاملClinical implication of T-wave morphology analysis as a new repolarization descriptor.
BACKGROUND T-wave morphology analysis (TMA) quantifies irregularities of ventricular repolarization based on singular value decomposition of the 12-lead electrocardiogram (ECG). Furthermore, TMA is useful for risk stratification of patients with myocardial infarction (MI), although gender differences in TMA and the relationship between TMA and heart diseases are unknown. The aim of this study w...
