摘要
目的探讨心电图中碎裂QRS(fQRS)波群在诊断陈旧性心肌梗死中的临床价值。方法将127例陈旧性心肌梗死患者按照有无fQRS波群分组,分析比较两组病理性Q波、频发室性期前收缩、室性心动过速、心室壁运动异常及左心室射血分数(LVEF)降低和冠状动脉狭窄(≥70%)的发生率。结果两组患者在除了病理性Q波发生率比较差异无统计学意义外,室性心律失常、冠状动脉狭窄、LVEF≤40%及心室壁运动异常比较差异均有显著统计学意义(均P<0.01)。结论 fQRS波群可作为心电图诊断陈旧性心肌梗死的一个新指标。
Objective To assess the clinical value of fragmented QRS complex （fQRS） in the diagnosis of old my-ocardial infarction （OMI）. Methods 127 patients with OMI were divided into groups with and without fQRS. Pathological Q-wave, frequency ventricular premature beat, ventricular tachycardia, abnormal ventricular wal motion, left ventricular ejection fraction and coronary artery stenosis （≥70%） were analyzed and compared. Results There was no significant difference of pathological Q-wave in two groups. The incidences of ventricular arrhythmia,coronary artery stenosis （≥70%）, reduced left ventricular ejection fraction （≤40%） and abnormal regional wal motion were significantly different be-tween two groups. Conclusion fQRS may be used as a new electrocardiographic sign in the diagnosis of OMI.
