急性心肌梗死QRS波时限与患者心功能及预后的关系

Relationship with Acute Myocardial Infarction in Patients with QRS Duration and Cardiac Function and Prognosis

目的：探讨急性心肌梗死（AMI）患者合并束支传导阻滞（BBB）的QRS波时限与心功能的关系。方法：选取2012年12月至2013年7月在玉田县医院住院治疗的AMI患者120例,根据入院期间患者泵功能情况,分为非泵衰竭组（KillipⅠ级）,泵衰竭组（KillipⅡ-Ⅳ级）,住院期间观察QRS波时限变化、Killip分级、BNP,2周内测定患者左室射血分数,住院病死率,探讨QRS时限与心功能及预后的关系。结果：与非泵衰竭组比较,泵衰竭组LVEF低、BNP水平高、QRS时限宽、住院病死率高,差异均有统计学意义（P〈0.05）.结论：AMI QRS波时限增宽预示患者心功能差、预后不良。

Objective：To investigate the acute myocardial infarction（AMI） patients with bundle branch block Relations（BBB） of QRS duration and cardiac function. Methods：Selected from December 2012 to July 2013 in Yutian County hospital treatment of 120 patients with AMI, according to the patient during hospitalization pump function was divided into non-pump failure group （Kil ipⅠlevel）, pump failure group （Kil ipⅡ-Ⅳlevel）, observed changes in QRS duration during hospitalization, Kil ip classiifcation, BNP, 2 weeks in patients with left ventricular ejection fraction was measured, inhospital mortality, and to explore the relationship between QRS duration and cardiac function and prognosis. Results：Group compared with the nonpump failure, pump failure group LVEF low and high levels of BNP, QRS width limit, inpatient mortality was high, the differences were statistical y signiifcant （P〈0.05）. Conclusion：QRS duration of AMI in patients with poor cardiac function widened indicates poor prognosis.
