本文观察了330例高血压合并冠心病患者(均经综合医院内科或心内科确诊)拔牙时心电图变化.共分为三组,每组110例,分别为含服硝苯吡啶10mg组,氨酰心安50mg组,及不服药的对照组.拔牙时心电图缺血性ST—T改变:在氨酰心安组有明显的改善作用,对室上性早搏也有减少作用;硝苯吡啶组对缺血性ST—T改变的改善作用不及氨酰心安,且对空上性早搏无减少作用.但氨酰心安组有三例出现P—R间期延长.
In this paper, 330 cases of hypertensive patients with coronary heart disease (both by General Hospital or cardiology confirmed ECG changes during tooth extraction were divided into three groups, 110 cases in each group were nifedipine 10mg group, Xinan 50mg group, and uncontrolled control group.Electrocardiogram ischemic ST-T changes during tooth extraction: alanine in the group had a significant improvement in the role of premature supraventricular premature beats have reduced the role of nifedipine group of ischemic The improvement of ST-T changes was not as good as that of alanyl-antilles, and no effect was found in the patients with SAP.However, there were three cases of prolonged P-R interval in patients with atenolol.
