     【摘要】 目的 探讨心率变异性(HRV)在不稳定型心绞痛(UAP)发病中的变化及临床意义。方法 对不稳定型心绞痛患者和正常人进行心率变异性分析。结果 UAP组的HRV多数指标均明显降低(P<0.01);正常人HRV具有昼夜节律变化,UAP组的HRV亦有昼夜节律变化,但降低;UAP患者行冠脉造影结果与HRV无相关性。结论 UAP患者HRV明显降低,测定UAP患者的HRV对评价其预后有一定的参考价值。

    【Abstract】 Objective To research the characteristics of heart rate variability(HRV) of patients with unstable angina pectoris(UAP) and effects of bisoprolol for HRV.Methods The HRV in patients with UAP and normal people were analyzed.Results All index of HRV decreased in patients with UAP compared with healthy people(P<0.01);The HRV in normal people has circadian rhythm changes and one in patients with UAP also had circadian rhythm changes,but decreased more;there was no relativity between the HRV and the results of coronary angiography in UAP.Conclusion HRV is of reference value for the progress of UAP patients,because HRV of UAP patients decrease more than that of the normal people.
