摘要
目的：探讨新兵首次高强度训练后的心电图变化及其特征。方法：选择426例入伍1个月的男性新兵,随机均分为强化训练组（当日清晨越野跑5km,时间控制在25-30min）和常规训练组（仅参加日常一般队列训练）。两组分别于训练前,训练后0.5h和24h记录常规12导联体表心电图,对比分析两组新兵训练前后心电图的变化。结果：与常规训练组比较,强化训练组训练后0.5h各种心律失常以及心电图改变发生率均显著升高,P〈0.05或〈0.01;训练后24h,强化训练组窦性心动过速（1.41%比6.57%）、窦性心动过缓（0.47%比5.16%）、频发房性早搏（0.94%比4.69%）、频发室性早搏（1.41%比5.16%）、房室传导阻滞（0.47%比4.23%）和ST-T改变（1.41%比6.10%）发生率仍然显著升高,P〈0.05或〈0.01。结论：新兵首次5km越野跑可出现心电图异常,包括心律失常和ST-T改变。
Objective：To explore changes and features of ECG in new recruits after first high intensity training.Methods：A total of 426 male new recruits who joined the army only one month were selected and randomly and equally divided into intensive training group（cross-country running for 5km at morning for 25-30min）and routine training group（only participated in daily general formation drill）.Both groups received routine 12-lead surface ECG before,and 0.5h,24 hafter training,ECG changes were compared and analyzed between two groups before and after training.Results：Compared with routine training group,there were significant rise in incidence rates of various arrhythmias and ECG changes in intensive training group on 0.5hafter training,P〈0.5or0.01;on 24 h after training,the incidence rates of sinus tachycardia（1.41% vs.6.57%）,sinus bradycardia（0.47%vs.5.16%）,frequent atrial premature beat（0.94%vs.4.69%）,frequent ventricular premature beat（1.41%vs.5.16%）,atrioventricular block（0.47%vs.4.23%）and ST-T changes（1.41%vs.6.10%）were still significantly higher in intensive training group,P〈0.05or0.01.Conclusion：Abnormal ECG,including arrhythmia and ST-T change,can occur in new recruits after first 5km cross-country running.
