摘　　要：目的研究符合Strauss新标准完全性左束支阻滞(CLBBB)在普通人群中的分布,为进一步明确心脏再同步化治疗(CRT)适应证提供依据。方法回顾性选择本院2009年至2015年住院患者中心电图诊断符合传统LBBB的患者共357例,按是否符合Strauss左束支阻滞新标准分为真性LBBB与非真性LBBB两组,统计并比较两组的年龄、性别、就诊科室分布、心血管合并症发生率、左室射血分数(LVEF)、室壁运动情况。结果非真性LBBB组151例,真性LBBB组206例。与非真性LBBB组比较,真性LBBB组年龄更小[(71.0±12.1)岁vs(73.9±10.0)岁],临床诊断心力衰竭的比例更低(11.7%vs 19.2%),室间隔厚度更高[(10.4±1.7)mm vs(9.8±1.6)mm],LVEF<0.35的比例更低(2.4%vs 7.3%)。结论符合Strauss LBBB新标准患者,行CRT时,将更加受益。Objective To further identification the indications of cardiac resynchronization therapy (CRT),the distribution of complete left bundle branch block(CLBBB)in the people was studied which was in accordance with the new standard of Strauss. Methods A total of 357 patients from 2009 to 2015 admitted to our hospital were selected in accordance with electrocardiogram diagnosis of traditional LBBB.And according to the new standard of Strauss left bundle branch block,they were divided into two groups:true LBBB and non-true LBBB.Then the Age,gender,distribution of medical departments,incidence of cardiovascular complications,left ventricular ejection fraction(LVEF)and ventricular wall movement were statistically compared between the two groups. Results 151 cases in the non-true LBBB group and 206 cases in the true LBBB group were studied.And compared with the non-true LBBB group,the true LBBB group was younger in age [(71.0±12.1)Y vs (73.9±10.0)Y] and the clinical diagnosis of heart failure was lower (11.7% vs 19.2%),the interventricular septum was thicker [(10.4±1.7)mm vs (9.8±1.6)mm],LVEF<0.35 was lower (2.4%vs 7.3%). Conclusion Patients who meet the new standard of strauss LBBB will have much more benefits if they have a CRT.
