摘　　要：目的:探讨采用单极标测对左右侧显性房室旁道射频消融的价值。方法:对110例左右侧显性房室旁道患者用大头导管标测时采用双极和单极同步记录,观察有效消融靶点时单极标测的特征。结果:单极标测房波(UP)、室波(UR)紧密相连,UP的降支与UR起始几乎融合,构成特征性的复合波-PQS波时射频消融成功率100%,放电次数明显减少。结论:采用单极标测,图形直观,不仅其图形易于迅速辩认,而且测量心室激动的提前时间与方法也较简单、准确,指导射频消融确定消融靶点有显著意义。Objectve:To investigate the value of unipolar mapping on the radiofrequency ablation of manifest accessory atrioventricular pathways.Methods:Recorded both unipolar and bipolar electrograms in 110 patients with left or right manifest accessory atrioventricular pathways,observed the characteristics of the unipolar electrograms when effective ablation target sites were found.Results:When the atrial wave(UP)and ventricular wave(UR)of unipolar mapping connected tightly and the descending branch of UP and the ons...
