The 12-lead electrocardiogram shows a broad range of abnormal patterns in trained athletes. The primary end point of this study was to investigate P wave dispersion, and P wave durations and related factors in different genders applying for registration to the School of Physical Education and Sports.
From 2006 to 2009, a total of 2093 students - 1674 boys with a mean age of 19.8 plus or minus 1.9 years and 419 girls with a mean age of 19.1 plus or minus 1.8 years - were included in the study. All 12 leads of the resting electrocardiogram were evaluated for P wave dispersion and electrocardiogram abnormalities. Baseline parameters such as age, body weight, body height, and body mass index, as well as electrocardiogram findings such as P wave maximal duration and P wave dispersion, were significantly higher in boys than in girls. Of all the parameters tested with correlation analysis, only gender (p = 0.03) (r = 0.04), body weight (p < 0.001) (r = 0.07), body height (p = 0.004) (r = 0.06), and body mass index (p = 0.01) (p = 0.05) were correlated with P wave dispersion.
The frequencies of all electrocardiogram abnormalities, P wave dispersion, and P wave maximal duration were higher in boys as compared with girls in an unselected student population applying for registration to the School of Physical Education and Sports; in addition, P wave dispersion was correlated with gender, body weight, body height, and body mass index.
12导联心电图在训练有素的运动员中显示出广泛的异常模式。本研究的主要终点是调查申请体育学院注册的不同性别的P波离散度、P波时限及相关因素。
2006年至2009年，共有2093名学生纳入研究，其中1674名男生，平均年龄19.8±1.9岁，419名女生，平均年龄19.1±1.8岁。对静息心电图的所有12个导联进行P波离散度和心电图异常评估。年龄、体重、身高和体重指数等基线参数，以及P波最大时限和P波离散度等心电图表现，男生均显著高于女生。在所有进行相关性分析的参数中，只有性别（p = 0.03）（r = 0.04）、体重（p < 0.001）（r = 0.07）、身高（p = 0.004）（r = 0.06）和体重指数（p = 0.01）（p = 0.05）与P波离散度相关。
在申请体育学院注册的未经过筛选的学生群体中，所有心电图异常、P波离散度和P波最大时限的发生率男生高于女生；此外，P波离散度与性别、体重、身高和体重指数相关。
