BACKGROUND: Previous studies have shown that atrial high-rate episodes (AHREs) after cardiac device implantation are associated with the occurrence of stroke. This study aimed to explore the predictive value of echocardiographic indices, namely left ventricular mass index (LVMI) and relative wall thickness (RWT), for AHREs following implantation of a cardiac implantable electronic device (CIED). METHODS: This was a single-center retrospective study. Patients who underwent initial dual-chamber permanent pacemaker implantation at the Fifth Affiliated Hospital of Sun Yat-sen University from January 1, 2020 to March 30, 2025, were included. Routine postoperative pacemaker programming was performed, and the occurrence of AHREs was set as the study endpoint. Based on whether AHREs were recorded in pacemaker programming, patients were divided into the AHREs group and non-AHREs group. Clinical baseline data, serological indicators, and echocardiographic indices were compared between the two groups. Spearman correlation analysis was used to evaluate the correlations between echocardiographic indices and permanent pacemaker implantation parameters (pacemaker threshold, pacemaker sensing, atrial output voltage). Cox regression analysis was conducted to identify independent predictors of AHREs. Receiver operating characteristic (ROC) curve analysis was performed to assess the predictive value of these indices for AHREs. Additionally, Kaplan-Meier survival analysis was used to compare the...
