We present the case of a 60-year-old female with a history of Ebsteins anomaly diagnosed at childhood admitted to our hospital for wide complex tachycardia. Programmed ventricular stimulation was negative. Electrophysiology study revealed an atrial rhythm and programmed atrial stimulation induced atrial tachycardia identical to the clinical tachycardia with multiple circuits . Radiofrequency ablation was not performed because of the technical difficulties. At two months follow up, the patients cardiac condition worsened and echocardiography revealed worsening tricuspid regurgitation. She underwent surgical repair. The postoperative course was uneventful.
