Abstract：Objective To investigate the detection situation and characteristics of abnormal ECGs of on-post staff and workers in enterprises and institutions during physical examination, and to provide references for their preventive health care. Methods We selected ECG data of 15 225 onpost staff and workers from Xiangcheng District, Suzhou who had undergone routine physical examination in 2022. Descriptive statistical analysis was performed on the population distribution characteristics and clinical features of abnormal ECGs by different sexes and ages. Results The overall detection rate of abnormal ECGs is 31.55%, mainly including sinus bradycardia (9.07%), ST-T changes (5.96%), right axis deviation (4.43%), left ventricular high voltage (2.58%), sinus tachycardia (2.40%), left axis deviation (1.89%), complete right bundle branch block (CRBBB, 1.66%), and nonspecific intraventricular block (1.25%). The detection rate of abnormal ECGs in males is higher than that in females, with statistically significant difference (P<0.05). The detection rate of abnormal ECGs in the 51-60 age group is higher than that in other age groups of the same sex (P<0.05); there is no statistically significant difference of detection rate of abnormal ECGs between males and females of the 51-60 age group (P>0.05). The detection rate of single abnormal ECG index shows significant difference between ages or sexes. Right axis deviation, sinus tachycardia, and short PR interval are more common in the 21-30 age group while sinus bradycardia, ST-T changes, left ventricular high voltage,left axis deviation, CRBBB, premature beats, first degree atrioventricular block, and left anterior fascicular block are more common in the 51-60 age group. In the females, the detection rates of ST-T changes, sinus tachycardia, and accelerated atrial escape rhythm are significantly higher than those in the males while in the males, the detection rates of sinus bradycardia, left ventricular high voltage, left axis deviation, CRBBB, nonspecific intraventricular block,first degree atrioventricular block, and prolonged P-wave duration are significantly higher than those in the females (P＜0.05). Conclusion The detection rate of abnormal ECGs is relatively high among onpost staff and workers in enterprises and institutions, which is closely related to age and sex. Regular physical examination and targeted health management help to prevent cardiovascular diseases among this kind of population.
