Abstract:
Objective To explore the effect of gender,training duration and type of sports on electro-cardiographic changes in Chinese elite athletes by performing electrocardiography(ECG).Methods A to-tal of 891 Chinese elite athletes who underwent ECG examinations between 2016 and 2019 were in-cluded in the study.The ECGs were divided into three groups according to the guidelines of the Euro-pean Society of Cardiology(ESC)in 2010:group 0(normal ECG),group 1(common and training-relat-ed ECG)and Group 2(uncommon and training-unrelated ECG).The effect of gender,training dura-tion(4 to 6 years,7 to 10 years and more than 11 years)and sports types(skill,strength,endur-ance and mixed categories)on the ECG changes was assessed.Results No significant differences were found in Group 2 in sex,training duration or sports types.However,the prevalence of common train-ing-related ECG changes was significantly higher in male athletes than in female athletes(58.9%vs.47.4%).Moreover,the highest prevalence was found in athletes with more than 11 years of training,significantly higher than those with 4-6 years of training(P<0.05).A highly significant difference was also observed among athletes of different sports(P<0.01),with the highest in those of the mixed cate-gory at 64.6%.Moreover,sinus bradycardia occurred with significantly higher incidence in athletes un-dertaking mixed and endurance training than others(P<0.05).Conclusion The training-related ECG changes of Chinese elite athletes is closely correlated to their gender,training duration and sports types.
