Ventricular Conduction Stability Noninvasively Identifies an Arrhythmic Substrate in Survivors of Idiopathic Ventricular Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Idiopathic ventricular fibrillation (VF) is a diagnosis of exclusion following normal cardiac investigations. We sought to determine if exercise‐induced changes in electrical substrate could distinguish patient groups with various ventricular ...
