摘　　要：目的：分析房性心动过速（房速）的电生理特点，探讨射频导管消融术在房速治疗中的价值。 方法：对２３例房速患者进行心电生理检查和射频导管消融治疗。 结果：２３例患者中，２０例为折返性房速，３例为自律性增高性房速。２３例患者，２１例消融成功，其中１９例成功靶点位于右心房，２例位于左心房。成功靶点 ＰＡ为－６０～－２５ ｍｓ，平均－３６ ｍｓ。 结论：射频导管消融术是治疗房速的安全有效的方法。Objective:To analyse the electrophysiological characteristics of atrial tachycardia(AT) and evaluate the value of ra- diofrequency ablation treating ATs. Methods :Electrophysiologic study and radiofrequency ablation were perfomed in 23 patients with ATs. Results:There were 20 cases of ATs with reentrent mechanism and 3 cases with abnormal automaticity. ATs were successfully ablated in 21 patients. The target sites of 19 cases were located in the right atrium and 2 cases in the left a- trium. The intervals between the local atrial wave at the target sites and the onset of p'wave in surface ECG were - 60 to - 25 ms,mean - 36 ms. Conclusion:Radiofrequency ablation is an effective and safe way to treat ATs.
