摘　　要：目的研究塔克拉玛干“沙漠人”心脏电生理特点。方法224名“沙漠人”进行静息心电图检查,男133名,女91名,对照组为151名,男76名、女75名。对受检者12导联静态心电图进行明尼苏达编码,相关数据采用χ2检验对率作趋势分析。结果(1)异常编码率:“沙漠人”组为103例(46%),男73例,女30例。(2)左室高电压(3-1,3-3)“沙漠人”组为73例(32·6%),(男55例,女18例),对照组为19例(12·6%),(男11例,女8例)。(3)高血压检出率,“沙漠人”为17例(7·6%),对照组59例(39·6%)。(4)“沙漠人”中超重和肥胖者21例(9·6%),对照组23例(23%)。(5)心律失常:“沙漠人”为20例(8·9%),对照组为10例(6·6%)。结论“沙漠人”左室高电压的检出率明显高于对照组,但高血压,肥胖检出率并不高,可能与其特殊的生存环境,要求强体力活动,心脏泵血功能高导致心肌生理性肥厚、胸壁薄有关。Objective To study the physiological characteristics and cardiac electrophysiology of the ＂desert people＂ in Taklimakan Desert, an isolated population of Uygurs. Methods Two Hundred and twenty-four out of the 1030 ＂desert people＂, 133 males aged 37.8 ± 17.5 （ 15 - 99 ） and 91 females aged 34.1 ± 12.1 （27 - 85） , underwent measurement of height, body weight, waist circumference, and blood pressure. Twelve-lead resting electrocardiogram was obtained and Minnesota coding was conducted. 150 Keriya Uygurs, 76 males aged 50.7 ± 15.6 （ 27 - 85 ） and 75 females aged 46.6 ± 11.7 （ 24 - 69 ） were used as controls. Results The abnormal Minnesota coding rate in the ＂desert people＂ as a whole was 46.0%, significantly higher than that of the controls （ 35.1%, P 〈 0.05 ）. In the ＂desert people＂, the abnormal Minnesota coding rate was 54. 9% in the males, significantly higher than that in the females （ 33.0% , P 〈 0.05 ）. In the control group, the abnormal coding rate was 28.0% in the females and 42. 1% in the males. The ECG high left R amplitude rate （code 3-1, 3-3） of the ＂desert people＂ as a whole was 32. 6% , significantly higher than that of the controls （ 12.6% , P 〈 0.001 ）. Within the ＂desert people＂ group, the ECG high left R amplitude rate of the females was 19. 8%, significantly lower than that of the males （41.2% , P 〈0. 005 ）. Within the control group, the ECG high left R amplitude rate of the females was 10.7%, not significantly different from that of the males （14.5% , P 〉0.5 ）. The hypertension rate of the ＂desert people＂ was 7.6%, significantly lower than that of the controls （ 36.4%, P 〈 0. 005 ）. The hypertension rate of the ＂desert people＂ coded as with left high R amplitude was 12.2%, significantly lower than that of the controls coded as with left high R amplitude （ 41.6% , P 〈 0. 005 ）. The overweight and obesity rate of the ＂desert people＂ was 9.6%, significantly lower than that of the controls （23%, P
