摘 要:目的:探讨P波离散度(Pd)对心功能不全患者阵发性心房颤动的辅助诊断价值。方法:选择我科2010-01~2012-01诊断为心功能不全的患者90例,分为观察组45例(有阵发性心房颤动)和对照组45例(无阵发性心房颤动);测量两组的最大P波时限(Pmax)、最小P波时限(Pmin)、P波离散度(Pd=Pmax-Pmin),并对可能的危险因素进行Logistic回归分析;用心脏彩色超声诊断仪测量两组的左心房内径,并进行比较。结果:观察组的Pmax、Pd显着高于对照组(P<0.05);Logistic回归分析显示,Pd、左心房内径是心功能不全患者的预测因子;两组的左心房内径比较差异均有统计学意义(P<0.05)。结论:Pmax、P波离散度、左心房内径是心功能不全患者心房颤动的独立预测因子,将它们联合应用对心功能不全患者患者心房颤动的临床诊断辅助价值较高。Objective:To expolor clinical value of P wave dispersion in diagnosis of cardia insufficiency patients with atrial fibrillation.Methods:One hundred cases patients with cardia insufficiency were divided into two groups.Forty-five Patients with Paroxysmal Atrial Fibrillation were in observation group,others in control group.Pmax、Pmin、Pd were conmpared and Logistics analysis were made.Left atrial diameter were measured in two groups.Results:Pd and left atrial diameter are predictive factors of cardia insufficiency.There were significant difference between two groups(P0.05)in above indexes.Conclusions:Pd and left atrial diameter are predictive factors of cardia insufficiency.Their combined application on cardia insufficiency patients with atrial fibrillation clinical diagnosis-aided higher value.
