摘　　要：目的探讨肝硬化者的自主神经功能变化。方法对129例肝硬化组(A组)和129例正常组(B组)进行心率变异(HRV)时域分析。结果 A组与B组比较,SDNN(77.16±32.83 vs 147.06±28.48m s)、SDANN(65.92±27.13 vs 124.21±34.77m s)、rMSSD(16.03±7.49 vs 35.15±16.05m s)、PNN50(1.73%±2.98%vs10.36%±7.42%)显著降低(P<0.01)。结论肝硬化者病变程度越重,HRV降低越明显。Objective To study autonomic nerve function in patients with liver cirrhosis. Methods Time domain methods of heart rate variability(HRV) tests were performed in 129 patients with liver cirrhosis and 129 normal subjects. Results SDNN(77.16±32.83 vs 147.06±28.48ms)、SDANN(65.92±27.13 vs 124.21±34.77ms)、rMSSD(16.03±7.49 vs 35.15±16.05ms)、PNN50(1.73%±2.98% vs 10.36%±7.42%)were significantly lower in patients with liver cirrhosis than those in normal subjects(P<0.01). Conclusion The more severe cirrhosic lesion is,the worse heart rate variability.
