单导管射频消融治疗频发房颤的预激综合征

采用单导管射频消支治疗１２例预激综合征（ＷＰＷ）。１２例中８例有反复快速性房颤史，３例须用同步直流以电复律，１例伴有晕厥。旁路分别为左侧８条，右后间隔２条，右后侧及右前间隔各１条，右侧者有１工存１条左侧隐匿旁路。全部旁践一次消融成功。术中未诱发房颤。随访５～１７月未见复发。

Single-catheter approach to radiofrequency current ablation of accessory pathway in Wolff-Parkinson-White syndrome with recurrent rapid atrial fibrillation]

Twelve patients with WPW were treated by single-catheter ablation. Eight patients had the histories of recurrent rapid atrial fibrillation(Af) and refractory to antiarrhythmic agents. Ventricular rate varied between 250-300 bpm. Defibrillation was needed in three patients, and one had syncope. All patients were treated successfully by ablation of accessory pathway with single-catheter approach and no Af occurred during the procedures. This result suggests that the single-catheter ablation may be an effective and feasible treatment for these patients with WPW and may be helpful in avoiding Af in multiple-catheter introducing procedure.
