New electromechanical substrate abnormalities in high-risk patients with Brugada syndrome

BackgroundThe relationship between the typical electrocardiographic pattern and electromechanical abnormalities has never been systematically explored in Brugada syndrome (BrS).ObjectivesThe aims of this study were to characterize the electromechanical substrate in patients with BrS and to evaluate the relationship between electrical and mechanical abnormalities.MethodsWe enrolled 50 consecutive high-risk patients with BrS (mean age 42 ± 7.2...
