房性心动过速的射频消融治疗及非接触球囊标测的作用

目的探讨房性心动过速临床和电生理特点及常规标测和非接触球囊标测射频消融治疗。方法对37例经电生理检查证实为房性心动过速的患者进行常规标测和非接触球囊标测下射频消融治疗，观察消融的成功率并进行随访观察其复发情况。结果37例房性心动过速35例经常规标测行射频消融成功30例，4例（其中2例经常规标测消融失败）经非接触球囊标测射频消融均成功，总的手术成功率为91．89％。随访（30．65±22．21）个月，2例复发，无严重并发症出现。结论射频消融治疗房性心动过速成功率高、并发症低，可作为房性心动过速的一线治疗，而非接触球囊标测则在一些特殊病例的消融中更具优势。

The Radiofrequency Ablation Treatment of Atrial Tachycardia and Effect of Non-contactional

Objective To study the chnic and electrophysiologic characteristic of atrial tachycardia and the efficacy of radiofrequency catheter ablation using conventional or non-contactional mapping. Methods A total of 37 patients with atrial tachycardia underwent radiofrequency linera ablation using using conventional or non-contactional mapping. The successful rate of RFCA and recurrence rate in follow-up were evaluated. Results Ablation with conventional mapping was performed successful in 30 of 35. Five cases were ablated ruccessfully with non-contactional mapping. The successful rate of ablation was 91.89%. Two cases recurred in （30.65 ± 22.21） months follow-up. No serious complication occurred. Conclusion Radiofrequency catheter ablation for atrial tachycardia have high successful rate and low complication and could recommend as first line treatment. Non-contactional mapping have superiority in some special cases.
