摘　　要：应用核素时相分析（ＲＰＡ）对１５例正常人及１７例预激综合征患者射频消蚀（ＲＦＣＡ）术前、术后进行了分析。结果表明：预激综合征患者ＲＦＣＡ术前心室相角程（ＶＷ）较术后及正常人明显增宽（Ｐ＜０．０１），而ＲＦＣＡ术后ＶＷ与正常人无显著差异（Ｐ＞０．０５）。ＲＦＣＡ术前、术后及正常人之间左心功能无显著差异（Ｐ＞０．０５）．ＲＰＡ对预激综合征的诊断，左、右侧旁路的定位与电生理检查相符．ＲＦＣＡ术成功后再作ＲＰＡ，１周以内预激点仍有残留，１周以后均恢复正常。提示：ＲＰＡ是诊断预激综合征、判定ＲＦＣＡ疗效及测定心功能的有效的、非创伤性的临床辅助检查方法之一。Radionuclide phase analysis(RPA) was carried out in 15 normals and 17 Wolff-Parkinson-White(W-P-W)syndrome before and after RFCA(radiofrequency ablation).VW(ventricular phase angle width) for the patients before RFCA were significantly wider than that for the normal group and the patients after RFCA(P<0.01), but there was no significant difference between normal group and the patients after RFCA(P>0.05). Also, no significant difference in the left ventricular cardiac function was observed among the normal subjects,before and after RFCA(P>0.05).The localization of bytract was correlated well with the electrophysiological study.Usually the pre--excite sites still existed within one week after RFCA, but disappeared after one week.In conclusion,RPA is a noninvasive,effective method for diagnosing W-P-W syndrome,estimating the effect of RFCA and detecting cardicac function.
