【摘要】：目的:用短程心率变异检测仪分析有更年期症状妇女的自主神经功能状态。其次,探讨无症状更年期妇女在绝经前后的自主神经功能变化。方法:收集2016年3-10月在山大一院处于更年期年龄段(40-60岁)的妇女,筛选在妇科门诊诊断为更年期综合征的患者57例收入有症状组(A组),把体检中心无更年期症状妇女61例收入无症状组(B组),B组依据是否绝经,进一步分为绝经前组(B1组)与绝经后组(B2组)。采用5min心率变异检测仪监测静息状态下的HRV,记录频域分析方法下每位受试者的高频功率(HF)、低频功率(LF)、低频标准化单位(LF%)、低高频功率比值(LF/HF)。使用两独立样本t检验分别比较A组与B组,B1组与B2组。结果:A组与B组间比较:相对于B组,A组HF明显升高(P0.05),而LF/HF、LF%明显降低(P0.05);B1组与B2组间比较:B2组HF、LF低于B1组(P0.05)。结论:与无症状更年期妇女相比较,有症状的更年期妇女副交感神经张力增高,交感神经张力降低,副交感神经功能处于明显优势地位;无症状更年期妇女中,绝经后自主神经的总体功能偏向交感,主因是副交感神经张力降低。
[Abstract]:Objective: to analyze the autonomic nervous function of women with climacteric symptoms by short range heart rate variability (HRV) instrument. To investigate the changes of autonomic nervous function in asymptomatic climacteric women before and after menopause. A total of 57 patients diagnosed as climacteric syndrome in gynecological outpatient clinic were selected as group A, and 61 women without climacteric symptoms in physical examination center were included in asymptomatic group B or B according to whether menopause or not. It was further divided into premenopausal group (group B1) and postmenopausal group (group B 2). HRVs in resting state were monitored by a 5 min HRV detector. The high frequency power, low frequency power and low frequency standardized single were recorded in frequency domain analysis method. Two independent sample t-tests were used to compare group A with group B, group B and group B.Results compared with group B, the HF of group A was significantly higher than that of group B: compared with group B, the HF of group A was significantly higher than that of group B, and that of group B was significantly lower than that of group B, and that of group B was significantly lower than that of group B (P < 0.05). Conclusion: compared with asymptomatic climacteric women, HFLF is lower than B1 group (P 0.05). In symptomatic climacteric women, the tension of parasympathetic nerve increased, the tension of sympathetic nerve decreased, and the function of parasympathetic nerve was in a dominant position, while in asymptomatic climacteric women, the overall function of autonomic nerve in postmenopausal women tended to be sympathetic. The main reason is the decrease of parasympathetic tension.
