Abstract：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.
