摘要
目的:分析心血管神经性晕厥的心率变异性。方法:随机选择50例心血管神经性晕厥患者作为观察组,并从同期健康体检的正常人群中随机选择50名作为对照组。所有研究对象均利用心电工作站记录分析系统,并进行编辑和校正,记录心率变异性并进行比较。结果:观察组在总体标准差、均值标准差与对照组差异均无统计学意义(P>0.05)。而2组差值均方的平方根和相邻间期差值大于50 ms的百分比差异均有统计学意义(P<0.01)。观察组在频域指标均显著低于对照组(P<0.01)。结论:心率变异性是评价自主神经活动的可靠指标,可以作为心血管神经性晕厥的一个极有价值的分析指标。
Objective： To analyze the application of heart rate variability in cardiovascular neurogenic syncope. Methods： Fifty patients with cardiovascular neurogenic syncope and 50 health people from healthy check-up crowd were divided into the observation group and control group,respectively. The heart rate variabilities between two groups were compared using electrocardiogram workstation. Results：The differences of overall standard deviation and mean standard deviation between two groups were not statistically significant（ P〈0. 05）. The differences of the square root in the difference between the mean square,and more than 50 ms of percentage in the difference between adjacent phase between two groups were statistically significant（ P〈0. 01）. The frequency domain indexes in observation group were significantly lower than that in control group（ P〈0. 01）. Conclusions： Heart rate variability is a reliable index to evaluate the autonomic nervous activity,which can be used as a valuable index of cardiovascular neurogenic syncope.
