摘　　要：目的：研究氨酰心安对急性心肌梗塞（Acute Myocardiald Infarction，AMI）QT离散度的影响。方法：40例AMI患者随机分成治疗组和对照组（n=20），治疗组给予氨酰心安25-150mg／d．对照给予常规治疗4周。比较两组治疗4周前后QT参数。结果：治疗4周后对照组QTd、QTcd、QTmax、QTmin、HR均无明显变化（P〉0．05），治疗组QTmax无改变（P〉0．5），QTmin延长（P〈0．01）．HR减慢（P〈0．01），QTd、QTcd缩短。结论：氨酰心可安延长AMI患者的QTmin，对QTmax无影响，使QTd减小，有利于AMI患者心肌电活动的一致和稳定，减少室性心律失常的发生。Objective： To study the effect of the atenolol to AMI QT dispersion degree. Method： 40 patients with AMI were divided into the treated group and the control group at randomly （ n = 20）, the treated group was given atenolol. The control group was treated as routine. Then compared the QT parameter of the four - week＇ s before - and - after. Result： After four weeks, there was no obviously change in the control group＇ s QTd,QTcd, QTmax,QTmin, HR, But in the treated group, unchanged in QTmax （ P 〉 0. 5 ）, pro- longed in QTmin（ P 〈0.01 ） ,slowed in HR（ P 〈0.01 ） ,shorted in QTD and QTcd. Conclusion ：The atenolol could prolonged the patients QTmin stabilized the QTmax, reduced the QTd, availed the AMI patients＇ myocardial electricity＇ s consistency and stabilization, then reduced the emergence of the ventricle arrhythmia.
