目的:了解美托洛尔在,心肌梗死治疗中的作用。方法:30例陈旧性心肌梗死患者应用口服美托洛尔治疗后观察QT 间期和QT间期离散性的变化。结果:治疗前后患者的平均QT间期和QT间期离散性有显著统计学差异(P<0．01)。结论: 通过测量心电图的QT间期和QT间期离散性可观察陈旧性心肌梗死患者服用美托洛尔药物后的疗效。
Objective: To understand the role of metoprolol in the treatment of myocardial infarction. Methods: Changes of QT interval and QT interval discrepancy were observed in 30 patients with old myocardial infarction treated with oral metoprolol. Results: The mean QT interval and QT interval dispersion of patients before and after treatment were significantly different (P <0.01). CONCLUSIONS: The efficacy of metoprolol in patients with old myocardial infarction can be assessed by measuring the QT interval and QT interval dispersion of the electrocardiogram.
