目的探讨地西泮在多层螺旋CT冠状动脉成像中稳定心率的效果。方法249例疑似冠心病患者按年龄分为45岁以下组,46～55岁组,56～65岁组,66～75岁组及76岁以上组,每组分为试验组及对照组,接受40层螺旋CT冠状动脉成像术,将检查时心率波动小于等于6次的作为有效,利用统计学方法,分别计算各组的P值,说明其有无显著性差异。结果45岁以下组,46～55岁组,56～65岁组存在显著性差异,66～75岁组及76岁以上组无显著性差异。结论地西泮与倍他乐克合用对部分人群能起到稳定心率的作用。
Objective To investigate the effect of diazepam on heart rate in multislice spiral CT coronary angiography. Methods 249 suspected coronary heart disease patients were divided into the following groups of 45 years old, 46 to 55 years old, 56 to 65 years old, 66 to 75 years old and 76 years old or older according to their age. Each group was divided into experimental group and control group, 40-slice spiral CT coronary angiography, check the heart rate fluctuations of less than or equal to 6 times as valid, the use of statistical methods were calculated for each group P value, indicating its significant difference. Results There were significant differences between 45 years old group, 46 ~ 55 years old group and 56 ~ 65 years old group. There was no significant difference between 66 ~ 75 years old group and 76 years old group. Conclusion Diazepam combined with Betaloc can stabilize heart rate in some people.
