研究发现急性心肌梗塞后自主神经系统的平衡发生紊乱，心率变异（ＨＲＶ）变小，猝死的危险性增大［１］。β受体阻滞剂可降低心肌梗塞病人的猝死率，但这种作用与ＨＲＶ的关系报道不多，因此我们观察了急性心肌梗塞病人应用阿替洛尔后ＨＲＶ的变化。１ 资料与方法１１ 一
Study found that after acute myocardial infarction autonomic nervous system disorders, heart rate variability (HRV) becomes smaller, the risk of sudden death increased [1]. β-blockers can reduce the rate of sudden death in patients with myocardial infarction, but this effect has few reports on the relationship with HRV. Therefore, we observed the changes of HRV in patients with acute myocardial infarction after atenolol administration. 1 Materials and Methods 1 1 a
