摘要
目的为制定中国成年健康女性心率正常参考值的统一标准提供科学依据。方法收集了中国87个单位测定的33 807例成年健康女性心率正常参考值,运用相关分析和回归分析的方法,研究了其与7项地理因素的关系。结果发现中国成年健康女性心率正常参考值与中国地理因素之间有很显著的相关关系(F=1.120,P=0.000)。用逐步回归分析的方法推导出了回归方程:Y=43.67+0.004000X_1+0.002000X_2+0.05400X_3+0.3350X_4+0.002000X_5+0.2330X_6-1.326X_7±35.41。在该回归方程中,Y是中国成年健康女性心率正常参考值(次/s),X_1是海拔高度(m),X_2是年日照时数(h),X_3是年平均气温(℃),X_4是年平均相对湿度(%),X_5是年降水量(mm),X_6是气温年较差(℃),X_7是年平均风速(m/s);35.41是剩余标准差的值。结论如果知道了中国某地的地理因素,就可以用回归方程计算这个地区的女性心率的正常参考值。依据中国成年健康女性心率正常参考值与地理因素的依赖关系,把中国分为8个区。
Objective Chinese female. Methods To provide a scientific basis for establishing a standard reference value of heart rate of The relationship between the reference value of 33807 healthy Chinese females and seven geographical factors in 87 areas of China was investigated. Results The geographical factors were correlated with the reference value of heart rate of Chinese female（F= 1. 120, P=0. 000）. One regression equation was obtained from mathematical regression analysis.. Y = 43. 67 ＋ 0. 004 000X1 ＋0. 002 000X2 ＋ 0. 054 00X3 ＋0. 335 0X4 ＋0. 002 000Xs ＋ 0. 233 0X6- 1. 326X7 ± 35.41. Conclusion The reference value of heart rate of Chinese female in a certain area can be reckoned from the geographical values obtained in this area. According to the similarity of the reference values of heart rate of Chinese female, there are eight geographical areas with distinctive heart rate values.
