    Analysis of deceleration capacity in healthy females

      摘要
    • 摘要: 目的 通过分析不同年龄女性人群心率减速力（DC）的昼夜变化，探讨年龄及昼夜节律对女性DC的影响。方法 339例健康女性按年龄分成4组：18~30岁（青年组），31~44岁（壮年组），45~55岁（围绝经期组），56~70岁（老年组）。各组人群行24 h动态心电图检查，计算机自动测定受捡人群24 h以及白昼（15:00~20:00）和夜间（00:00~05:00）的DC值并进行心率变异性（HRV）分析。结果 随着年龄增长，女性24 h DC、HRV及HR均呈降低趋势；各年龄组女性夜间DC以及RMSSD值均显著高于白天；DC与HR以及SDNN、RMSSD密切相关。结论 健康女性的DC随着年龄增长而下降，且呈昼夜节律变化；DC与HRV密切相关。

       

      Abstract: AIM To analyze the deceleration capacity (DC) in healthy females and to explore the effects of age and circadian rhythm on DC. METHODS We collected the average heart rate (HR), DC and time domain parameters of heart rate variability (HRV) (SDNN, RMSSD) for 24 h, both day- (15:00-20:00) and night- (00:00-05:00) time, respectively, from 24-h Holter recordings in 339 healthy females aged 18 to 70 years. According to age, subjects were divided into four groups, young (18-30 years), middle-age (31-44 years), perimenopausal (45-55 years) and older group (56-70 years). RESULTS DC, HRV and HR generally decreased with age. DC and RMSSD were significantly higher at night in all age groups. DC showed a significant correlation with HR, SDNN and RMSSD. CONCLUSION DC declines with age and shows regular changes following circadian rhythm. Moreover, DC is closely correlated with HRV.
