Electrophysiological Registry Duesseldorf

Overview

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.

This is a single-center observational registry including all patients treated with EPS, catheter ablation, or electrical cardioversion at the Department of Cardiology, Pneumology, and Angiology, University Hospital Düsseldorf. Retrospective data from 2011 onward and prospective data from 2015 onward are collected. The registry systematically records demographic data, comorbidities, laboratory and imaging results, procedural details, and follow-up outcomes. Patients are routinely followed at 1, 3, 6, 12, and 24 months after the procedure. Additional follow-up may be performed by telephone interview with patients or referring physicians to improve data quality. Primary endpoints focus on safety (peri- and postprocedural complications, late adverse events) and efficacy (recurrence of arrhythmias, need for repeat procedures, pacemaker implantation, or new medications). Secondary endpoints include hospitalization and all-cause mortality. Participation does not alter routine diagnostic or therapeutic decisions, and no additional invasive procedures are performed. Data will be used for quality assurance and to improve understanding of prognostic factors, with the ultimate aim of optimizing future patient care.
