【摘要】 目的 :探讨 β受体阻滞剂对冠心病患者QT离散度的影响。 方法 :对照组常规抗心肌缺血治疗 ,实验组常规抗心肌缺血治疗加用阿替洛尔。结果 :实验组治疗后QTmax无改变 (P >0 0 5 ) ,心率显著减慢 (P <0 0 1) ,QTmin延长 (P <0 0 1) ,QTd、QTcd缩小 (P <0 0 5 )。结论 :β受体阻滞剂可缩小冠心病患者QT离散度 ,有效降低其猝死率更多还原

【Abstract】 OBJECTIVE: To investigate the effects of β receptor blocking drugs on QT dispersion on patients with coronary heart disease. METHODS: Contrd group was treated by routine antiischemia methed, experimental group was treated by routine method and added Atenolol. RESULTS: After treatment, in experimental groups, QT max didn’t change(P>0 05), rate of heart lowered obviously (P<0 01), QT min prolonged (P<0 01), QT d and QT cd lessened (P<0 05). CONCLUSION: β receptor blocking drugs can reduce QT dispersion in patients with coronary hear disease and reduce the rate of sudden death effectively.更多还原
