Radiofrequency Catheter Ablation of Paroxysmal Supraventricular Tachycardia: Experience in 100 Patients
陣發性心室上頻脈之導管電燒術治療：100例之經驗
摘要
本研究之目的是為評估陣發性心室上頻脈的病人接受經導管電燒術治療之安全性與效力，並調查其短期或中期之追蹤結果。從1996年7月至1998年1月經心電圖記錄證實為陣發性心室上頻脈共100位病人（52位男性與48位女性，平均年齡48±18歲，年齡範圍11至84歲）接受導管電燒術治療，病人依其頻脈機轉分為兩組：第一組為房室結迴旋頻脈（AVNRT，24位男性與32位女性，平均年齡52±18歲，年齡範圍15至81歲）；第二組為房室迴旋頻脈（AVRT，29位男性與17位女性，平均年齡43±17歲，年齡範圍11至84歲）。本研究之電燒總成功率為99%（除一位表現型AVRT之病人外），有一位病人發生電燒術相關之併發症，此名病人產生輕度心包膜積水，但並無心包填塞之徵候發生。在術後追蹤期內（最長期間達17個月），包括19位病人因心悸症狀接受心電生理學檢查，無一例復發。本研究顯示經導管電燒術治療心室上頻脈為一非常有效和安全之方法，而且此治療方法之併發率及復發率皆非常低。

This study was conducted to evaluate the safety and efficacy of radiofrequency catheter ablation (RFCA) on patients with paroxysmal supraventricular tachycardias (PSVT) and to investigate the short- or intermediate-term follow-up results. From July 1996 to January 1998, a total of 100 patients (52 men and 48 women with a mean age of 48±18 years, range 11-84) with PSVT were subjected to RFCA. They were classified into two groups: Group I, atrioventricular nodal reentrant tachycardia (AVNRT, 24 men and 32 women with a mean age of 52±18 years, range 15-81); and Group II, atrioventricular reentrant tachycardia (AVRT, 29 men and 17 women with a mean age of 43±17 years, range 11-84). The success rate of RFCA was 99%. The only failure occurred in a patient with AVRT. Only 1 patient had a procedure-related complication. This patient who manifested AVRT developed mild pericardial effusion, which resolved spontaneously. In the follow-up periods (up to 17 months), 81 patients had no recurrent palpitations. The remaining 19 patients who had symptoms suggestive of recurrent PSVT underwent follow-up electrophysiologic studies. Neither AVNRT nor AVRT was induced in the 19 patients. In conclusion, RFCA is a highly effective and safety treatment for patients with supraventricular tachycardias.
