摘　　要：目的 :探讨倍他乐克对急性心肌梗死 (AMI)患者心率变异性 (HRV)的影响。方法 :60例AMI患者随机分为 2组 ,试验组 2 8例进行常规加用倍他乐克治疗 ,对照组 3 2例常规治疗。结果 :试验组HRV的平均R R间期的标准差 (SDANN)、平均R R间期的变异数 (CV)、相邻周期长度之差大于 5 0ms所占比例 (PNN)、所有相邻周期长度平方差的平均总和的平方根 (RMDD)较对照组增加 ,低频域 (LF)、低频 /高频 (LF/HF)较对照组降低 (P <0 0 5或P <0 0 1)。结论 :AMI患者早期给予倍他乐克治疗能使患者HRV明显增加 ,有助于改善预后 。Aim: To study the effect of betaloc on heart rate variability (HRV) in patients with acute myocadial infarction (AMI). Methods:60 AMI patients were devided into 2 groups at random. 32 patients given routine treatment as a control group, 28 patients given routine treatment plus betaloc as a treatment group. Results: The SDANN、 CV、 PNN、 RMDD of HRV in the treatment group increased more than those of the control group, while LF、 LF/HF decreased compared with those of the control group ( P <0 05 or P <0 01). Conclusion: The HRV of AMI patients who were treated with betaloc in the earlier stage increased obviously. Betaloc can improve prognosis and reduce the rate of sudden death.
