Exercise-induced ventricular ectopy with RBBB morphology suggests underlying myocardial fibrosis in inherited left ventricular cardiomyopathy.
INTRODUCTION AND OBJECTIVES Inherited left ventricular cardiomyopathies (iLVC) are genetic disorders characterized by myocardial remodeling and fibrosis, predisposing patients to ventricular arrhythmias. The prevalence of exercise-induced right bundle branch block-pattern ventricular ectopy (EI-RBBB-VE) and its relatio...
