广州地区城市农村人群心电图比较——5663例心电图明尼苏达编码分析

Comparison of Electrocardiogram Between Urban and Rural Populations of Guangzhou ——Analysis of Electrocardiogram Minnesota Codings From 5 663 Cases

目的：比较广州地区城乡人群心电图差异并分析其可能的原因。方法：用明尼苏达编码方法，对５６６３例３５～６４岁城乡男女心电图进行编码和分析对比。结果：总异常编码频率，城市男性为１７．２６％、城市女性１７．８３％、农村男性１８．７７％、农村女性１７．８８％，城乡间和男女间均无显著差别，而在主要单项编码中，两者均存在显著差异，大部分编码频率随年龄增大而增加。结论：人群心电图反映出人群间存在有疾病谱或生理特征的差异。高血压与左心室高电压及ＳＴ－Ｔ改变有较密切关系。

Objective:To compare the electrocardiogram (ECG) between urban and rural populations in Guangzhou district and explore its possible causes. Methods:ECG tracings of 5 663 cases taken from Guangzhou urban and rural populations were coded with Minnesota code and analyzed. Results:The rates of total abnormalities were 17 26%,17 83% in urban males and females,and 18 77%,17 88% in rural males and females,respectively.There were no significant differences between urban and rural people as well as between males and females.For major single code,the differences between urban and rural people,or between males and females were of statistical significance.The frequencies increased with aging in most codes. Conclusion:The population ECG might reflect the differences of disease pattern or physiological characteristics of the population.Hypertension is highly related to left ventricular high voltage and ST T changes.
