摘要 目的: 评价Iwa方案和St.Georege方案对显性预激综合征单旁道体表心电图的定位价值。方法: 预激综合征经心电生理检查证实为单旁道并且行射频消融术成功者共21例(左侧旁道10例、右侧旁道11例)。术前心电图分别分析40msδ波极性、QRS波群形态等指标,用Iwa及George方案定位后与消融成功靶点对比分析。结果: 两方案各具特点,定位符合率Iwa方案为85%,George方案为76%，未见显著差异(P>0.05)。结论: Iwa方案和Georege方案均具有较高的定位价值。

Abstract Objective: To evaluate the value of Iwa and St.Georege algorithms for identifying accessory pathway in Wolff-Parkinson-White(W-P-W) syndrome.Methods: Twenty one cases(10 of left side accessory pathway and 11 of the right) were retrospectively analyzed by correlating resting 12-lead eletrocardiogram(ECG) with the successful radiofrequency catheter ablation target site of sigle anterogradely conducting accessory pathway in W-P-W syndrome.The ECG findings included the initial 40 msec of the delta wave and QRS wave amplitudes.The characteristics of two algorothms were studied and compared each other.Results: Overall accuracy of Iwa algorithm was 85%,while Georege algorithm was 76%.There is no significant difference between the two algorithms.Conclusion: The two algorithms above are available to localize accessory pathway in W-P-W syndrome.
