Objective To explore the correlation between ST-segment depression,ST-T changes,and atrial premature beats(APB)or premature ventricular contraction(PVC).Methods By univariate and multivariate Logistic regression analysis,retrospective analysis was conducted on clinical ECG data to determine the relationship between ST-segment depression,ST-T changes,and APB or PVC.Results Analysis of the ECG data from 4 952 patients revealed a significant correlation of ST-segment depression and ST-T changes with APB and PVC.Among the patients with ST-segment depression,the incidences of APB and PVC separately increased to 9.00 and 13.65 times the incidences in the patients without ST-segment depression.Among the patients with ST-T changes,the incidences of APB and PVC separately increased to 27.60 and 22.00 times the incidences in the patients without ST-T changes.Multivariate Logistic regression analysis also found that ST-segment depression of up to 0.05 mV and ST-T changes were key factors influencing the occurrence of APB and PVC.Conclusion ST-segment depression and ST-T changes may serve as risk factors for the occurrence of APB and PVC.
