摘　　要：目的探讨收缩功能不全并完全性左束支传导阻滞患者QRS时间与左心室质量的关系。方法将57例左心室收缩功能不全并完全性左束支传导阻滞患者按QRS时间分为120～160ms（观察组，n=42）及〉160ms（对照组，n=15）两组。常规超声心动描记术计算左心室质量。观察两组QRS时间与左心室质量的关系。结果两组患者左心室质量分别为（220．68±87．26）g、（32246±9269）g，差异有非常显著性意义（P〈0．01），QRS时间与左心室质量呈正相关（r=0．28，P〈0．05）。结论收缩功能不全并完全性左束支传导阻滞患者QRS间期延长反映左心室质量增加。Objective To explore relationship between QRS duration and left ventricular mass eft ventricular systolic dysfunction and complete left bundle branch block （CLBBB）. Methods （ LVM ） in patients with 57 cases with CLBBB were divided into two groups based on QRS duration ≤or 〉 160ms. LVM was calculated on an echocardiogram and compared between the two groups. Results LVM in two groups was （220.68 ±87.26）g and （322.46 ±92.69）g, respectively. There was significant difference between them（P 〈 0.01 ）. QRS duration was significantly correlated with LVM （r=0.28,P 〈 0.05）. Conclusion Prolongation of QRS duration may reflect LVM increasing in patients with left ventricular systolic dysfunction and CLBBB.
