P wave dispersion is an independent predictor of atrial fibrillation. P wave dispersion is associated with inhomogeneous and discontinuous propagation of sinus impulses. The purpose of this study was to investigate P wave dispersion and transthoracic echocardiographic findings in elite women basketball players.
We recruited 27 well-trained woman athletes with a training history of many years (11.9 +/- 3.6 years). All of the athletes were elite women basketball players and they were regularly maintaining sportive activities and training programs. Twenty-six age and sex matched healthy sedentary subjects consisted of control group. The difference between P maximum and P minimum durations was defined as P wave dispersion. The echocardiographic parameters were assessed in detail in the standard left lateral decubitus position.
The body height, body weight, body surface area, metabolic equivalent, maximum P wave duration and P wave dispersion were increased in the elite basketball athletes as compared with healthy sedentary subjects. On the contrary; the heart rate, ejection fraction and interventricular septum thickness in diastole were decreased in athletes. The body height (p=0.006, r=0.37), body weight (p=0.04, r=0.28), body surface area (p=0.01, r=0.33) and heart rate (p=0.01, r=-0.32) were correlated with P wave dispersion.
P wave dispersion was increased in elite woman basketball players as compared with healthy sedentary subjects. P wave dispersion was correlated with heart rate, body height, body weight and body surface area.
P波离散度是心房颤动的独立预测因子。P波离散度与窦性冲动的不均匀和不连续传播有关。本研究的目的是调查精英女子篮球运动员的P波离散度和经胸超声心动图检查结果。
我们招募了27名训练有素、有多年训练史（11.9±3.6年）的女性运动员。所有运动员均为精英女子篮球运动员，她们定期进行体育活动和训练计划。26名年龄和性别匹配的健康久坐不动的受试者组成对照组。P波最大时限与最小时限之差定义为P波离散度。在标准左侧卧位详细评估超声心动图参数。
与健康久坐不动的受试者相比，精英篮球运动员的身高、体重、体表面积、代谢当量、最大P波时限和P波离散度均增加。相反，运动员的心率、射血分数和舒张期室间隔厚度降低。身高（p=0.006，r=0.37）、体重（p=0.04，r=0.28）、体表面积（p=0.01，r=0.33）和心率（p=0.01，r=-0.32）与P波离散度相关。
与健康久坐不动的受试者相比，精英女子篮球运动员的P波离散度增加。P波离散度与心率、身高、体重和体表面积相关。
