摘　　要：目的 探讨持续性心房颤动合并逸搏及逸搏节律患者的RR-Lorenz散点图特征.方法 回顾性分析2005年7月至2013年4月在郑州大学第二附属医院24 h动态心电图诊断为持续性心房颤动的患者291例,分析其RR间期及QRS波形.将患者分为2组：A组患者心房颤动不合并逸搏及逸搏节律,共259例;B组患者心房颤动合并逸搏及逸搏节律,共32例.观察2组患者的RR-Lorenz散点图形态特征.结果 （1）A组患者的RR-Lorenz散点图呈“扇形”.（2）在B组中,30例患者的RR-Lorenz散点图呈“扇形”,合并“曲尺”、45＆#176;角上1个致密短棒,逸搏所占比例为0.28％ （275/98 369） ～ 14.06％（11 263/80 112）;其余2例患者的RR-Lorenz散点图无此典型特征.结论 依据24h动态心电图的RR-Lorenz散点图“扇形”合并“曲尺”及致密棒典型特征,可直观、快速、定性诊断持续性心房颤动合并逸搏及逸搏节律.Objective To explore the characteristics of RR-Lorenz plot in persistent atrial fibrillation （AF） patients complicating with escape beats and rhythm though ambulatory electrocardiogram.Methods The 24-hour ambulatory electrocardiogram of 291 persistent AF patients in second affiliated hospital of Zhengzhou university from July 2005 to April 2013 were retrospectively analyzed and the RR interval and the QRS wave were measured.Patients were divided into two groups according to the distribution of the RR-Lorenz point [AF without escape beats and rhythm group （Group A,n =259） and AF with escape beats and rhythm group （Group B,n =32）].The characteristics of RR-Lorenz plot between the two groups were compared.Results （1） Fan-shaped RR-Lorenz plots were evidenced in Group A.（2） In Group B,30 cases showed fan-shaped with L-shaped and a short dense rods along 45° line.The proportion of escape beats and rhythm was 0.28% （275/98 369）-14.06% （11 263/80 112）.The other 2 cases in group B showed no typical RR-Lorenz plots features.Conclusion RR-Lorenz plot could help to quickly diagnose persistent AF complicating with escape beats and rhythm according to the typical RR-Lorenz plot characteristics in 24-hour ambulatory electrocardiogram.
