Objective: To assess the ECG changes and arrhythmias seen in Ebstein’s patients.
Design: Retrospective longitudinal cohort.
Setting: University Hospital of Wales (UHW).
Population/Participants: 74 patients managed at UHW between 1990 and 2020.
Results: 53 cases eligible for the study were included. Right bundle branch block was seen in 65.2%, and delta wave in 18.8%. Wolff Parkinson White syndrome occurred in 17% of patients, and other types of supraventricular tachycardia in 17% of patients. 13.2% of patients experienced atrial fibrillation, 9.4% experienced atrial flutter and 1.9% had broad complex tachycardia. Postoperative heart block was seen in 44.4% of tricuspid valve repair patients, and 50% of tricuspid valve replacement patients.
Conclusions: Coexisting arrhythmias are common amongst Ebstein’s patients, with Wolff Parkinson White syndrome being most prevalent. Right bundle branch block was the most common ECG finding, followed by delta wave.
