摘要 目的研究年轻健康男性心率变异性。方法收集2001~2009年在我室参加临床药物试验的205例年轻健康男性的动态心电图(DCG)资料,分析年轻健康男性的心率变异性。结果时域指标:平均RR间期的标准差(SDNN)、相邻RR间期差的均方根(rMSSD)、相差大于50ms的相邻RR间期占RR间期总数的百分比(PNN50)分别为184.8±42.7(80~297)ms、30.2±18.8(7.3~89)ms、19.0±10.4(1~51);频域指标:日间低频成分(LF)、高频成分(HF)、及二者的比值(LF/HF)分别为719.0±504(.74~2575)ms2、289.8±306.3(25~1772)、3.2±1.6(0.4~7.91),夜间LF、HF、LF/HF分别为650.6±480.9(20~2468)ms2、971.8±870.0(24~5489)、1.1±1.2(0.1~8.3),日间HF较夜间低,而LF、LF/HF较夜间高,差异有统计学意义(p〈0.0001)。结论本研究结果在一定程度上为明确年轻健康男性心率变异性各参数的正常值提供了参考依据。 Objective To study heart rate variability(HRV) of health young man.Method Record and analyze heart rate and HRV in 24 hour Holter recording in 205 health young men.Results The standard deviation of all RR intervals(SDNN),the square root of the mean squared differences of successive of RR intervals(rMSSD),the percentage of of successive of RR intervals 50ms(PNN50) were 184.8±42.7(80~297) ms,30.2±18.8(7.3~89) ms,19.0±10.4(1~51),low frequency(LF),high frequency(HF) and LF/HF in daytime were 719.0±504.0(74~2575) ms2,289.8±306.3(25~1772) and 3.2±1.6(0.4~7.91),while those in night were 650.6±480.9(20~2468) ms2,971.8±870.0(24~5489) and 1.1±1.2(0.1~8.3).There were significant difference between day and night.Conclusion The present study can provided some useful information about HRV in health young man.
