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 clinical significance of ECG QRS wave duration prolongation in patients with chronic heart failure of coronary heart disease. Methods A total of 330 CHD patients with chronic heart failure were enrolled in this study. According to QRS wave duration of ECG, they were divided into two groups: ≥120ms group and <120ms group. The relationship between QRS wave duration and NYHA functional class, left ventricular ejection fraction (LVEF) Short axis fractional shortening (LVFS), left atrium and left ventricular size, left ventricular wall thickness, mitral regurgitation, ventricular conduction block and hospital mortality. Results ① The LVEF, LVES, LAD and LVEDd in the QRS wave duration> 120ms group were both greater than the QRS duration <120ms group; ② The heart function grading, hospital mortality, wall thickness, bundle branch block and the incidence of atrioventricular block No significant difference. Conclusion Electrocardiogram QRS wave duration of coronary heart disease in patients with congestive heart failure has a certain clinical significance.
