摘　　要：目的评价高原世居藏族健康成人心率及心率变异性时域指标的特点。方法对100例高原世居藏族健康成人,75例西宁地区藏族健康成人和100例西宁地区汉族健康成人进行全程24h动态心电图检查,分析心率指标(24h总心搏数、24h最小心率、24h最大心率和每分平均心率)和心率变异性(Heartratevariability,HRV)时域指标(SDNN、SDANN、SDNNindex、rMSSD和pNN50)。结果高原世居藏族健康成人心率指标:24h总心搏数、24h最大心率、每分平均心率均低于西宁地区藏、汉族健康成人。高原世居藏族健康成人的心率变异时域指标rMSSD、pNN50高于西宁地区藏、汉族健康成人。结论高原世居藏族健康成人心率偏慢,世居藏族迷走神经活性略高。Objective The results of heart rate and heart rate variability （HRV） were analyzed and compared among native healthy Tibetan adults at ahiplano （3800m altitude） and healthy Han and Tibetan adults in Xining（2260m altitude）. Methods 100 native healthy Tibetan adults at altiplano,75 healthy Tibetan and 100 Han adults in Xining took a Holter check-up to obtain indexes of heart rate （total heart beats, maximal heart rate,minimal heart rate during 24 hours and mean heart rate per minute）and HRV＇s indexes of time domain （SDNN,SDANN,SDNNindex,rMSSD,pNN50）, Result The heart rate data of native Tibetan adults at altiplano：total heart beats,maximal heart rate during 24 hours,mean heart rate per minute are less than hearthy Tibetan and Han people adults in Xining. The HRV＇s data of native hearthy Tibetan adults such as rMSSD,pNN50 are higher than hearthy Tibetan and Han adults in Xining. Conclusion The heart rate of native hearthy Tibetan adults is slightly slow,their activity of vagal nerve is a little higher.
