房室结双径路患者的心率变异性分析

Heart rate variability of dual atrioventricular nodal pathway

目的:探讨有无房室结双径路的两组患者心率变异性之间的关系。方法:对通过心内电生理检查确诊的76例AVNRT和73例AVRT患者两组间的一般临床资料和心率变异性指标进行对比分析。结果:1与旁道组对比,房室结双径路组以女性为主;2双径组TP、VLF和LF、LF/HF皆高于旁道组,HF低于对照组。3男性中双径组TP、VLF、LF、LF/HF皆高于旁道组。4女性中双径组LF高于旁道组,HF低于对照组,LF/HF显著高于对照组(P<0.05)。结论:1房室结双径路患者女性发病构成比高。2房室结双径路患者的心率变异性增高。3房室结双径路女性患者交感神经张力增高而副交感神经张力降低,男性患者主要以交感神经张力增高为主。

Objective :To compare cardiac autonomic regulation in patients with a history of paroxysmal AVNRT and AVRT .Methods:76 AVNRT patients and 73 AVRT patients had undergone Intracardiac electrophysio-logical study(EPS) .The two groups were age matched .Cardiac autonomic regulation was assessed by means of fre-quency domain analysis of heart rate variability at rest .Results :①The AVNRT group has higher rate of female pa-tient .②The AVNRT group has higher levels of TP、VLF、LF and LF/HF ratio ;And had lower levels of HF .③In the male patients ,the TP、VLF、LF and the LF/HF of AVNRT is all higher .In female ,the LF、LF/HF were all higher in AVNRT group;And the HF was lower(P<0 .05) .Conclusion :① The AVNRT group has higher rate of female patient .②The HRV is higher in the AVNRT group .③ The sympathetic nerver’s tone is higher in female AVNRT patients but the vagal tone were lower ;And the male AVNRT patients mainly has higher sympathetic nerve’s tone .
