EDEN Intracardiac Electrogram Recording and Classifying System

Study Description: The study tests a hardware electrocardiography appliance used to record and classify intracardiac electrograms obtained in the practice of medicine. No diagnoses or clinical decisions are based on the findings in this study. Objectives: The primary objective is to determine whether the classifier accurately identifies the EDEN radial depth category. Endpoints: Primary endpoint: The primary endpoint is classifier accuracy. Exploratory endpoints: Correspondence of EDEN electrograms with CT and CMR findings (of myocardial segmental thickness, scar, and possibly relaxometry); Impact of abnormal conduction, induced or observed during the EP procedure, on EDEN electrogram morphology. Technical success of acquiring and classifying EDEN electrograms.
