摘要
目的探讨心电图QRS波时限延长在冠心病慢性心力衰竭患者中的临床意义。方法入选330例冠心病慢性心力衰竭患者,根据心电图QRS波时限分为≥120ms组和<120ms组,分析两组患者QRS波时限与NYHA心功能分级、左心室射血分数(LVEF)、左室短轴缩短分数(LVFS)、左心房及左心室大小、左室壁厚度、二尖瓣返流、室内传导阻滞和住院死亡率间的关系。结果①QRS波时限>120ms组LVEF、LVES、LAD、LVEDd均大于QRS时限<120ms组;②两组间心功能分级、住院死亡率、室壁厚度、束支阻滞及房室阻滞发生率等无显著差异。结论心电图QRS波时限对判断冠心病并发慢性心力衰竭患者病情具有一定临床意义。
Objective To investigate the value of QRS duration extension for patients with heart failure of coronary heart disease. Method Enroll 330 patients with with heart failure of coronary heart disease, divided in two groups for QRS duration ≥ 120ms or 〉120ms. Analysis of LVEF, LVES, morality, the sizes of atrial and ventricular, the ventricular wall thikness, evaluating the relationship between QRS duration extension and above index. Results ①LVEF, LVES, LAD, LVEDd in patients with QRS duration 〈120ms group were higher than〉 120ms group. ②There was no difference between two groups for NYHA class, motrality, incidence of AVB or branch block, and Mitral regurgitation. Conclusion It is useful for QRS duration extension to evaluate the patients with heart failure of coronary heart disease.
