摘　　要：目的探讨快速性房性心律失常患者红细胞分布宽度（RDW）与左心房内径（LAD）的关系。方法选择2013年10月至2014年8月在我院行动态心电图检查证实为快速性房性心律失常患者,搜集RDW、心脏彩超等临床资料,回顾性研究RDW与LAD的关系。结果根据RDW值由低到高三等分组,组间比较RDW、LAD存在显著性差异（P〈0.05）,随RDW值增高左心室舒张期末内径和LAD增高。Pearson相关分析显示,RDW水平与房性心律失常Kleiger分级（r=0.280,P=0.000）、LAD（r=0.297,P=0.000）呈正相关;以快速性房性心律失常（Kleiger分级1~3级=0,Kleiger分级4~6级=1）为因变量进行二分类Logistic多元回归分析显示,RDW（OR=1.215）、LAD（OR=1.024）是快速性房性心律失常的危险因素。结论快速性房性心律失常患者RDW与LAD具有相关性,两者均为快速性房性心律失常的危险因素。Aim To investigate the relationship between red cell distribution width（RDW）and left atrial diameter（LAD）in patients with atrial tachyarrhythmia. Methods This retrospective study included 460 patients with atrial tachyarrhythmia from October 2013 to August 2014. The patients＇ RDW and echocardiography results were collected to investigate the relationship between RDW and LAD. Results Patients were divided into three groups by sorting RDW values in an ascending order. RDW value,LAD value had significant difference among these groups（P〈0. 05）. With increased RDW,the LAD value gradually elevated. Pearson correlation analysis was applied to control other influencing factors,and multiple correlation analysis showed that LAD was positively correlated with RDW（r = 0. 297,P = 0. 000）.With atrial tachyarrhythmia（Kleiger class 1 ~ 3 = 0,Kleiger class 4 ~ 6 = 1）as a dependent variable,binary classification Logistic multivariate regression analysis showed that RDW（OR = 1. 215）and LAD（OR = 1. 024）were risk factors for atrial tachyarrhythmia. Conclusion RDW is independently correlated with LAD in patients with atrial tachyarrhythmia.
