摘　　要：为寻求显性预激综合征病人更好的体表心电图旁道定位法,分析44例经射频导管消融术成功治疗的垦性预激综合征单支旁道病人术前窦性心律心电图的δ波及R/S,按照Chern-En Chiang等人提出的心电图分步规则系统旁道定位法预测旁道的部位,并与射频消融手术确定的旁道相比较。结果显示:该旁道定位法的总敏感性为97.2％,特异性为92.1％,准确度为93.1％。认为该旁道定位法对于术前预测旁道部位具有一定的临床实用价值。In order to discuss better localization of accessory pathway in patients with Wolff-Parkinson-White syndrome shown in electrocardigraph, we analysed elec-trocardiographic delta waves and R/S ratio during sinus rhythm before radiofreqnency catheter ablation in 44 patients with Wolff-Parkinson-White syndrome who had been proved to have a single accessory pathway by successful radiofrequency catheter ablation, and prelocated accessory pathway according to a step-wise electrocardiographic algorithem suggested by Chern-En Chiang et al, and made comparison with localization of accessory pathway by radiofreqency catheter ablation. Our results have shown that rates of sensitivity, specificity and accuracy of this stepwise electrocardiogrpahic algorithem are 97.2%, 92.1% and 93.1% respectively. We consider this stepwise algorithem has a conciderable practical value in localizing accessory pathway.
