摘要
目的 探讨急性心肌梗死 (acutemyocardialinfarction ,AMI)患者QT离散度 (QTd)的变化及倍他乐克对其影响。方法 入选 5 0例AMI患者 ,应用倍他乐克 4周并与健康对照组比较。结果 两组间用心率正后的QT离散度(QTcd)、AMI伴与不伴室性心律失常患者间 ,倍他乐克治疗前后QTcd均有显著差异。结论 AMI患者QTcd可增加 ,倍他乐克可显著缩小QTd。
Objective To study the variation of QT dispersion (QTd) of the patients with acute myocardial infarction (AMI) and the effects of Betalock.Methods Fifty cases of AMI were given Betalock for four weeks and compared with the contrast group.Results The QTcd between the two groups, AMI accompanying and not accompanying ventricular arrhythmia,had significant difference (P<0.01, P<0.05, P<0.01) before and after treatment. Conclusions QTcd patients with AMI increase and Betalock can decrease QTcd.
