Abstract：Objective To investigate the electrocardiogram (ECG) status of officers and soldiers stationed at high altitude and analyze its correlation with age, altitude and training time. Methods The ECG reports were randomly selected from the physical examination reports of 575 officers and soldiers in Aba prefecture, Sichuan Province. The altitude, training time and age were taken as grouping variables. All the ECG reports were reviewed and corrected by the same cardiologist with senior title to form the final ECG reports and the abnormal ECG were recorded. Results Among all the ECG reports, there were 238 abnormal ones, accounting for 41.39%, with 188 cases of sinus bradycardia, accounting for 32.70%, and 109 cases of sinus arrhythmia, accounting for 18.96%. There were 28 cases of other abnormal ECG, accounting for 4.87%, including 13 cases of ST segment changes, 4 cases of bundle branch block, 3 cases of T wave changes, 2 cases of atrioventricular block, 2 cases of atrial premature beats, 1 case of atrial fibrillation, 1 case of frequent ventricular premature beats, 1 case of abnormal Q wave and 1 case of P wave widening. There was no significant difference in the incidence of sinus bradycardia and sinus arrhythmia among different age groups, different altitude groups and different training time groups (P>0.05). There was significant difference in the incidence of other abnormal ECG between different altitude groups and different training time groups (P<0.05).The incidence rate increased with the increase of altitude and training time. Conclusion Among the ECG abnormalities in officers and soldiers stationed on plateaus sinus bradycardia and sinus arrhythmia are the main types, which have no correlation with age, altitude and training time. The incidence of other abnormal ECG types is low, but it is positively correlated with altitude and training time, which needs to be paid more attention and trained scientifically.
