平面和断层核素时相分析对预激综合征旁道的定位诊断价值

The planar and tomographic phase analysis in Wolff-Parkinson-White syndrome

用核素门控心血地显像对20例拟行射频消融术的预激综合征（WPW）患者进行平面时相分析，其中14例加做断层时相分析。用平面和断层时相分析对WPW旁道进行定位，并分别同射频消融术所证实的旁道定位和心电图的旁道定位对比。结果表明，核素时相分析对分道定位有较高的准确率，断层时相分析优于平面时相分析和心电图，核素时相分析还展示了“潜在性”旁道和多旁道定位的能力，能为射频消融术提供更多有价值的信息。

Planar gated blood pool scintigraphy was performed in 20 patients with WolffPark inson-White syndrome, in which a new method of tomographic phase analysis was performed in 14 patients. The abnormorl intial contractions in both planar and tomographic phase images were compared with the sites of ACP based on ECG and radiofrequency ablation. Tomographic phase analysis could detect the sites of ACP more precisely than planar phase analysis and ECG.Nuclear phase analysis seems to be a promising method to detect the site of ACP, especially for patients with multiple ACPS.
