Electrocardiographic Characteristics of Patients with Ebstein's Anomaly Before and After Ablation of an Accessory Atrioventricular Pathway

The abnormal development of the tricuspid valve in patients with Ebstein's anomaly results in several activation abnormalities including delayed intraatrial conduction, right bundle branch block (RBBB), and ventricular preexcitation. The aim of the present study was to define the ECG characteristics before and after ablation of an accessory A‐V pathway (AP) in patients with Ebstein's anomaly. Methods: A series of 226 consecutive patients with...
