摘要 对30例(22例左侧旁道、8例右侧旁道)房室折返性心动过速患者在射频消融前后进行心率变异分析,旨在了解射频消融房室旁道前后心脏植物神经张力的改变.结果显示左侧旁道患者消融后 LFP/HFP显著性增高,提示副交感神经张力相对减低,交感神经张力相对增高.但右侧旁道患者消融后心率变异无变化.关于射频消融左侧旁道心率变异的机理及左、右侧旁道消融后心率变异变化存在差异的原因有待阐明. Heart rate variability was analyzed in 30 patients(22 LAP. 8 RAP) with AVRT before and after ra-diofrequency ablation of atrioventricular accessorypathways to observe change of innervation of cardiacautonomic nervous system. Results showed that LFP/HFP increased significantly in patients with LAP afterLAP ablation, suggesting a relative decrease in vagalactivity and a relative increase in sympathetic activity.However, there was no change in HRV after RAP ab-lation. Further elucidation is needed in exploring themechanism of change of HRV after LAP ablation and cause of difference between LAP and RAP in change of HRV after ablation.
