Changes of Myocardial Markers,Cardiac Function and Arrhythmia in Soldiers with Asymptomatic Arrhythmia after High-Intensity Military Training
Objective To explore the changes of cardiac function,myocardial markers and arrhythmia in soldiers with asymptomatic arrhythmia after high-intensity military training.Methods Totally 73 asymptomatic arrhythmia soldiers and 75 healthy soldiers were included.Before and after high-intensity military training,their myocardial markers,cardiac ultrasound,and dynamic electrocardiogram were measured,and the changes in relevant indicators before and after the training were analyzed.Results After high-intensity training,CK isoenzyme,and creatine kinase increased compared to before training(all P<0.001),but did not reach the pathological warning value.The case group and control group showed a slight decrease in ejection fraction after training,but the clinical changes were not significant(both P>0.05).In 24-hour dynamic electrocardiogram,the total number of heart beats,average heart rate,and number of supraventricular premature beats significantly increased after high-intensity training(all P<0.05).Conclusion High intensity military training can increase the frequency of supraventricular premature beats in asymptomatic arrhythmia patients.
