一名 30 岁女性，患有 Ebstein 异常，表现为持续、宽 QRS 波心动过速，表现出左束支传导阻滞形态。 系列电生理学研究揭示了许多传统抗心律失常药物难以治疗的右束支和左束支折返性心动过速。 右束支射频和直流导管消融未能控制心动过速。 随后，该患者接受了广泛的右束支心内膜冷冻消融术，从而治愈了她的心律失常。
A 30-year-old woman with Ebstein's anomaly presented with a sustained, wide QRS complex tachycardia exhibiting a left bundle branch block morphology. Serial electrophysiological studies revealed right and left bundle branch reentry tachycardias refractory to many conventional antiarrhythmic drugs. Radiofrequency and direct current catheter ablation of the right bundle branch failed to control the tachycardias. The patient subsequently underwent extensive endocardial cryoablation to the right bundle branch resulting in cure of her arrhythmia.
