目的:探究我院不明原因心悸患者的动态心电图和心率变异性情况。方法:选择2014年6月-2015年5月之间前往我院检查和治疗的126例原因不明心悸患者作为观察对象(研究组),选择同期健康体检的100例健康人作为对照组。均采用连续动态心电图检查并予以心率变异性分析。对两组的结果进行对比。结果:两组患者的平均心率差异小,无统计学意义(P<0.05);研究组患者的SDNN以及SDANN等指标对比对照组的差异大,具有显著统计学意义(P<0.05)。结论:不明原因心悸患者的心率与健康人的差异较小,但是通过心率变异性分析可见患者的心脏自主神经功能受损,应予以重视。
Objective: To investigate the ambulatory ECG and heart rate variability in patients with unexplained heart palpitations in our hospital. Methods: One hundred and sixty-six patients with unexplained palpitation who visited our hospital from June 2014 to May 2015 were selected as the observation group (study group), and 100 healthy people were selected as the control group during the same period. Continuous dynamic electrocardiogram were used and heart rate variability analysis. The results of the two groups are compared. Results: There was no significant difference in average heart rate between the two groups (P <0.05). There were significant differences between SDNN and SDANN in the study group and the control group (P <0.05). Conclusion: The heart rate of patients with unexplained heart palpitations is less than that of healthy people. However, the analysis of heart rate variability shows that patients with impaired cardiac autonomic nervous function should pay more attention.
