This registry at University Hospital Düsseldorf collects retrospective and prospective (from 2019 onward) data on patients undergoing electrophysiological studies (EPS), catheter ablation, and electrical cardioversion. The primary goal is to evaluate safety, efficacy, and clinical outcomes of these standard procedures in routine care. Data will be used for quality assurance and to identify prognostic patient- and procedure-related factors.
