对河北省体育局自行运动管理中心的5名一级和12名集训自行车运动员进行安静心电图测试，探索不同运动水平自行车运动员的安静心电图特征。结果显示：一级自行车运动员平均安静心率为50.8±9.42次/min，集训运动员平均安静心率为59.8±4.12次/min，不同运动水平运动员之间心率具有显著性差异；整体窦性心动过缓发生率为59%，一级水平运动员心动过缓发生率为80%，集训水平运动员心动过缓发生率为50%，二者具有显著性差异。与正常人ECG判断标准相比运动员心电图QRS波群电压增高、心率降低、QTc值增大、ST段抬高，其他指标均在正常人指标范围内。自行车运动员上述心电图特点是运动员心脏的生理适应，是良好心力储备的表现。自行车运动员的心电图异常改变主要有：QT间期异常（长QT间期、QT间期）5例，占29.4%，2例心室预激，2例电轴右偏。所以需要加强运动员的心电图监控，医务监督。

To explore quiet electrocardiogram characteristics of cyclists in different sports level , we chose five level 1 and twelve training cyclists from bicycle sports management center in Hebei province to do electrocardiogram test in rest state. Results: The average?resting heart rate?of bicycle athletes in level 1 was 50.8+9.42/min,?the average?resting heart rate?of training?athletes was 59.8+4.12/min. There was significant difference of heart rate in resting between bicycle athletes in different training level. The overall incidence of sinus bradycardia was 59%. The average incidence of sinus bradycardia of bicycle athletes in level 1 was 80%, and the average incidence of sinus bradycardia of cyclists in training was 50%. The difference was significant. To compare the test results of athletes with the general ECG standard , the electrocardiogram QRS complex voltage increased, the heart rate reduced, the QTc value increased, and ST segment increased. Other indicators indexes were in the normal range. The ECG changes indicates electrocardiogram physiological adaptation of athlete and were a sign of better heart reserves. Electrocardiogram (ECG) abnormal changes of cyclists mainly included: QT abnormal interphase (long QT, QT) in 5 cases, accounted for 29.4%, ventricular pre-excitation syndrome in 2cases , and 2 cases of starboard electrical axis. To strengthen the electrocardiogram (ECG) monitoring and medical supervision of athletes is necessary.
