短PR间期在正常人群的分布特点

目的探讨短PR间期在正常人群中的分布特点及其影响因素。方法回顾性分析5258体检者,分析其心电图PR间期及QRS波群特点,总结PR间期缩短者的性别及年龄分布特征。结果 5258例中体检人群中,80例呈现PR间期缩短,其中男性26例（0.8%）,19-29岁4例;30-39岁11例;40-49岁6例;50-59岁3例;60-69岁2例,女性54例（2.6%）19-29岁7例;30-39岁10例;40-49岁24例;50-59岁11例;60-69岁2例。结论短PR间期在正常人群中发病率为1.5%,可能是正常心电图的一种变异,此外,短PR间期在男女发病率间有差异,可能与激素水平有关。

Short PR interval in the normal population distribution of characteristics

Objective To investigate the short PR interval in the normal population distribution of characteristics and factors. Methods Retrospective analysis of 5258 health examination, analysis of the electrocardiogram PR interval and QRS complex characteristics, summarized PR interval shortened by sex and age distribution. Results of5258 casesin the medicalpopulation, 80 patients showing shortened PR intervalsyndrome, in which 26 males（0.8%）, between 19~29 year-old 4 cases; 30~39 year-old in 11 cases; 40~49 year-old 6 cases; 50 ~59 year-old 3 cases; 60~69 year-old 2 cases, female 54 cases（2.6%） 19~29 year-old 7 cases; 30~39 year-old 10cases; 40~49 year-old 24 cases; 50~59 year-old 11 cases; 60~69 year-old 2 cases. Conclusions short PR interval in the normal population incidence rate of 1.5%, may be a variant of the normal electrocardiogram, in addition, short PRintervalsyndromeincidencebetween men and women aredifferent, and hormonelevelsmayberelated.
