In this brief report, we provide normal reference ranges for PR duration [unadjusted and heart rate adjusted] and P-wave indices [duration, amplitude and terminal force in V1] in individuals free of cardiovascular disease and its risk factors. We used automatically processed digital ECG data from 1252 US participants [mean age 59 (± 10) years, 738 women, 588 whites, 207 African-Americans, 217 Hispanics, 240 Chinese] from the Multi-Ethnic Study of Atherosclerosis [MESA]. In multivariable adjusted linear regression models with PR and each P-wave variable as a separate outcome, significant age, sex and race differences in these markers were observed. Subsequently, we report reference ranges for abnormal [2nd and 98th percentiles], borderline abnormal [5th and 95th percentiles] and mean [SD] values of PR and P-wave indices stratified by age [middle age (45-64 years) and seniors (65-84 years)], sex [men and women] and race [whites, African Americans, Hispanics and Chinese].
在本简要报告中，我们给出了无心血管疾病及其危险因素个体的PR间期[未校正及心率校正]和P波指标[V1导联的时限、振幅及终末电势]的正常参考范围。我们使用了来自动脉粥样硬化多民族研究[MESA]的1252名美国参与者[平均年龄59 (± 10)岁，738名女性，588名白人，207名非裔美国人，217名西班牙裔，240名华裔]自动处理的数字心电图数据。在以PR间期和每个P波变量作为单独结果的多变量校正线性回归模型中，观察到这些指标存在显著的年龄、性别和种族差异。随后，我们报告了按年龄[中年(45 - 64岁)和老年人(65 - 84岁)]、性别[男性和女性]和种族[白人、非裔美国人、西班牙裔和华裔]分层的PR间期和P波指标的异常[第2和第98百分位数]、临界异常[第5和第95百分位数]以及均值[标准差]的参考范围。
