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).<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n This was a single\u2010center retrospective study. Patients who underwent initial dual\u2010chamber permanent pacemaker implantation at the Fifth Affiliated Hospital of Sun Yat\u2010sen 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\u2010AHREs 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\u2013Meier survival analysis was used to compare the cumulative incidence of AHREs among groups with different levels of RWT and LVMI.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 122 patients were included, and 45 patients developed AHREs during the follow\u2010up period. Early diastolic mitral inflow E\u2010wave velocity (\n r<\/jats:italic>\n \u00a0=\u00a00.297,\n p<\/jats:italic>\n \u00a0<\u00a00.001) and right atrial parameters (\n r<\/jats:italic>\n \u00a0=\u00a00.280,\n p<\/jats:italic>\n \u00a0=\u00a00.002) were positively correlated with pacemaker sensing parameters, with statistically significant yet weak correlations. Univariate Cox regression analysis revealed significant correlations between the occurrence of AHREs and early diastolic tricuspid inflow E\u2010wave velocity, fractional shortening (FS), RWT, diastolic wall strain (DWS), LVMI, and type of cardiac remodeling (all\n p<\/jats:italic>\n \u00a0<\u00a00.05). Multivariate Cox regression analysis demonstrated that lower RWT (\n B<\/jats:italic>\n \u00a0=\u00a0\u22127.576,\n p<\/jats:italic>\n \u00a0=\u00a00.007) and higher LVMI (\n B<\/jats:italic>\n \u00a0=\u00a00.013,\n p<\/jats:italic>\n \u00a0=\u00a00.003) were associated with an increased risk of AHREs. ROC curve analysis showed that the area under the curve (AUC) of LVMI and RWT for predicting AHREs were 0.722 and 0.716, respectively. Kaplan\u2013Meier survival analysis indicated that patients with LVMI \u00a0\u2265\u00a0114.930 or RWT <\u00a00.392 had a higher incidence of AHREs within 5 years after dual\u2010chamber permanent pacemaker implantation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n In our study, echocardiographic indices were correlated with permanent pacemaker implantation parameters. LVMI and RWT are independent predictors of AHREs. Patients with LVMI \u2265\u00a0114.930 or RWT\u00a0<\u00a00.392 after cardiac device implantation have a high incidence of AHREs, which provides a basis for early clinical intervention.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/echo.70363","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T14:30:53Z","timestamp":1765377053000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Left Ventricular Mass Index and Relative Wall Thickness Predict Atrial High\u2010Rate Episodes in Patients With Pacemaker Implantation"],"prefix":"10.1111","volume":"42","author":[{"given":"Qin","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Cardiology The Fifth Affiliated Hospital of Sun Yat\u2010Sen University Zhuhai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Limin","family":"Xiang","sequence":"additional","affiliation":[{"name":"Department of Ultrasound The Fifth Affiliated Hospital of Sun Yat\u2010Sen University Zhuhai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gege","family":"Zhao","sequence":"additional","affiliation":[{"name":"Medical Insurance Department The Fifth Affiliated Hospital of Sun Yat\u2010Sen University Zhuhai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enbo","family":"Zhan","sequence":"additional","affiliation":[{"name":"Department of Cardiology The Fifth Affiliated Hospital of Sun Yat\u2010Sen University Zhuhai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiali","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Ultrasound The Fifth Affiliated Hospital of Sun Yat\u2010Sen University Zhuhai China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"issue":"9","key":"e_1_2_10_2_1","first-page":"1528","article-title":"Atrial Fibrillation and Heart Failure With Reduced Ejection Fraction: New Assessment of an Old Problem","volume":"12","author":"Zeitler E.
