Investigation in abnormal changes of T wave in electrocardiogram of children and the influencing factors
Objective To investigate the status quo and influencing factors of abnormal changes of T-wave in electrocardiogram of children in the department of cardiology.Methods A retrospective study was used.A total of 3 571 children were chosen as the study subjects,who were admitted to the Department of Cardiology of Hunan Children's Hospital from January 2019 to December 2023,and they were divided into abnormal T-wave group(n=749)and control group(n=2 822)according to whether they had abnormal T-wave or not.The types of T wave abnormalities,age distribution,gender ratio and some other indicators were analyzed,and correlation analysis was carried out by statistical methods to explore the possible influencing factors.Results A total of 3 571 children in the Department of Cardiology were included,including 749(20.97％)with abnormal T-wave.T-wave abnormalities occurred mainly in 350 cases of pericarditis(46.73％),followed by 157 cases of myocarditis/cardiomyopathy(20.96％).There was no statistically significant difference in gender or age between the two groups(P＞0.05).The proportion of overweight in the abnormal T-wave group was higher,and there was statistically significant difference(P＜0.05).The proportion of respiratory system diseases,digestive system diseases,neurological diseases and infectious diseases in abnormal T-wave group was higher,the difference being statistically significant(P＜0.05).Logistic regression analysis showed that body mass(overweight),combination with respiratory diseases/digestive diseases/neurological diseases,pericarditis,and myocarditis/cardiomyopathy were independent risk factors for abnormal changes of T-wave in electrocardiogram of children in the Department of Cardiology(P＜0.05).Conclusion Abnormal changes of T wave in electrocardiogram are more common in children in the cardiology department,and the children with pericarditis and myocarditis/cardiomyopathy are more prone to such abnormalities.Meanwhile,attention should also be paid to the children with respiratory diseases,digestive diseases,and neurological diseases,for the risk of abnormal changes of T-wave in their electrocardiograms is also higher.
