摘　　要：应用核素位相分析(PA)评价射频消蚀治疗预激综合征(WPW)的疗效。18例 WPW 患者射频消蚀治疗前后用PA 观察异位激动点变化。术前所有患者均显示有异位激动点。术后12例患者异位激动点消失,4例逐步消失,提示射频消蚀成功;2例无变化,提示射频消蚀失败。PA 能直观地准确判断射频消蚀术前后异位激动点的变化,因此是一种非创伤性、安全、简便、准确、可靠评价 WPW 患者射频消蚀疗效的方法。PURPOSE Whether radionuclide phase analysis (RPA) could evaluate the effect of radiofrequency current ablation (RFCA) in patients with Wolff-Parkinson-White (WPW) syndrome was evaluated.METHODS 18 patients with WPW syndrome were studied using RPA pre-and post-RFCA.RESULTS RPA identified the sites of preexcitation in all patients before RFCA. Compared with the pre-RFCA study,the sites of preexcitation disappeared in 12 cases,disappeared gradually in 4 cases and un- changed in 2 cases.50 RFCA was successful in the former two patterns,but failed in the last pattern.CONCLUSIONS RPA can evaluate the changes of preexcitation sites in patients with WPW syndrome before and after RFCA.It was a noninvasive and reli- able method for assessing and monitoring the effect of RFCA in patients with WPW syndrome.
