摘　　要：目的:观察研究年轻健康正常人的静息桡动脉脉搏波特征及单次个体化运动后脉搏波的变化情况。方法:选取阜外医院年轻健康、无任何疾病诊断的正常人16例,首先完成症状限制性极限心肺运动试验(CPET),根据CPET计算Δ50%功率为个体化精准运动强度,完成持续30 min的单次运动。于运动前和运动后10 min、20 min、30 min分别测量50 s桡动脉脉搏波,先用软件自动定点再人工复检得到每个脉搏波特征点:起始点(B)、主波波峰点(P1)、重搏波波谷点(PL)、重搏波波峰点(P2)、结束点(E),从仪器中导出各点对应的横坐标(时间T)和纵坐标(幅值Y)的原始数据,将上一个脉搏波的结束点E视为下一个波的起始点B,TB归零,得到主要观察指标:YB、YP1、YPL、YP2及TP1、TPL、TP2、TE,并计算出ΔYP1(YP1-YB)、ΔYPL(YPL-YB)、ΔYP2(YP2-YB),TE-TPL、(TE-TPL)/TPL、脉率,S1(主波升支斜率)、S2(重搏波升支斜率),ΔYP2-ΔYPL、TP2-TPL作为次要观察指标;定义波峰明显的重搏波为YP2>YPL,计算波峰明显的重搏波出现率(50 s内YP2>YPL的波形个数/波形总个数×100%);对每位患者运动前后的50 s脉搏波数据个体化分析,再将所有数据求均值进行整体分析。结果:①16例年轻健康受试者(男10女6),年龄(30.6±6.4,24~48)岁;身高(170.4±8.2,160~188)cm;体质量(63.9±12.8,43~87)kg。②静息时YB(87.2±5.8,78.1~95.9)、YP1(223.5±15.8,192.7~242.3)、YPL(122.8±7.8,110.0~133.8)、YP2(131.4±4.9,116.7~137.5)、TP1(126.2±42.2,94.2~280.0)、TPL(360.2±44.8,311.5~507.3)、TP2(432.4±50.8,376.2~589.0)、TE(899.7±86.9,728.3~1042.0);ΔYP1(136.3±19.9,96.8~158.6)、ΔYPL(35.7±10.7,16.0~55.7)、ΔYP2(44.3±8.1,22.5~56.5)、TE-TPL(539.5±79.3,405.9~691.3)、(TE-TPL)/TPL(1.5±0.3,0.8~2.0)、脉率(67.3±6.6,57.6~82.4)、S1(1.1±0.2,0.6~1.4)、S2(0.1±0.1,0.0~0.2)、ΔYP2-ΔYPL(8.6±6.1,0.9~19.8)、TP2-TPL(72.3±19.9,38.3~108.4)。③运动后10 min,YPL(97.0±13.2比122.8±7.8)、YP2(109.6±12.8比131.4±4.9)、ΔYPObjective:To observe and study the resting radial artery pulse wave and the pulse wave changes after a single individualized exercise in young healthy normal subjects.Methods:We selected 16 young healthy graduate students,advanced training doctors,and visiting scholars from Fuwai Hospital without any disease diagnosis and low daily exercise.They first completed the symptom-restricted limit cardiopulmonary exercise testing(CPET).A single individualized exercise withΔ50%power as the exercise intensity was completed within one week after CPET.We measured and recorded 50 s pulse wave data before exercise and 10 min,20 min,30min after exercise,let the instrument automatically fix the point and then manually recheck to obtain each pulse wave characteristic point:starting point(B),main wave peak point(P1),trough of a repulse point(PL),crest of a repulse point(P2),and end point(E),and the raw data of the abscissa(time T)and ordinate(amplitude Y)corresponding to each point were derived from the instrument.We treated the end point E of the previous pulse wave as the start point B of the next wave,returned TB to zero,and got the main observation indicators:YB,YP1,YPL,YP2 and TP1,TPL,TP2,TE,and calculated outΔYP1(YP1-YB),ΔYPL(YPL-YB),ΔYP2(YP2-YB),TE-TPL,(TE-TPL)/TPL,pulse rate,S1(the slope of main wave ascending branch),S2(the slope of dicrotic ascending branch),ΔYP2-ΔYPL and TP2-TPL as secondary observation indicators;defined the dicrotic wave with obvious crest as YP2>YPL,and calculated the occurrence rate of dicrotic wave with obvious crest(number of waveforms with YP2>YPL in 50 s/total number of waveforms×100%).We analyzed individually the 50 s pulse wave data of each subject before and after exercise,and then averaged all the data for overall analysis.Results:①16 healthy young subjects(males 10,females 6),age(30.6±6.4,24~48)years old;height(170.4±8.2,160~188)cm;body mass(63.9±12.8,43~87)kg.②YB(87.2±5.8,78.1~95.9),YP1(223.5±15.8,192.7~242.3),YPL(122.8±7.8,110.0~133.8),YP2(131.4±4.9,116.7~137.5),TP1(126.
