摘要
目的 探讨老年退行性心脏瓣膜病 (SDHVD)患者心率变异性 (HRV)的改变。 方法 对SDHVD组5 1例 ,健康老年人组 5 0例进行HRV时域分析。 结果 与健康老年人比较 ,SDNN、SDANN ,RMSSD ,PNN5 0均显著降低 (P <0 0 5 )。 结论 HRV可作为评估SDHVD患者预后的手段。HRV降低的SDHVD患者易发生心脏事件 。
Objective To investigate change of heart rate variability(HRV) in patients with senile degenerative heart valvular disease(SDHVD) Methods Time domain indexes of HRV were compared in two groups:SDHVD group(n=51) and elderly healthy people(n=50) as the control group Results Patients in SDHVD group were significantly lower than the control group in SDNN,SDANN,RMSSD and PNN50(P<0 05) Conclusion HRV could be used to evaluate the prognosis of patients with SDHVD,and the prophylactico therapeutic measure must be adopted for them
