摘　　要：通过对15例正常对照组与46例预激综合症患者进行平面核素心室造影位相分析、了解正常人位相起始点与扩播过程后,以对预激组患者进行旁道定位,并与电生理标测进行对比.结果表明:位相分析对旁道的检出率为82.5%,对13例诱发室上性心动过速后,使检出率提高到93%.由于平面核素位相分析可多次重复检查,因此,可作为旁道定位的一种无创诊断筛选以及疗效判断的手段.To evaluate the value of detecting accessory pathway using planner radionuclide ven-triculography phase analysis (PRNV-PA), 15 normal subjects and 46 patients with Wolff-Parki-son-White (w-p-w) syndrome were performed PRNV-PA. Compared with electrophysiologic locating, the accuracy of detecting accessory pathway by PRNV-PA was 82. 5% during basic conduction and increased to 93% during pacing supra-ventricular tachycardia (SVT). In conclusion, PRNV-PA is a reliable and noninvasive method for locating accessory pathway and estimating the therapeutic effect of ablation.
