摘要
目的探讨碎裂QRS波(fQRS)与心肌梗死患者心功能的关系。方法选取2017年1月至2020年1月无锡市惠山区人民医院发生急性心肌梗死的63例住院患者作为研究对象,行心电图筛查,根据心电图结果分为观察波组(有fQRS波,28例)和对照组(无fQRS波,35例),比较两组患者心功能检查相关数据,分析有无fQRS与心肌梗死患者心功能的关系,评估出现fQRS对患者左室收缩功能的影响。结果观察组左室射血分数(LVEF)低于对照组,差异有统计学意义(P<0.05)。观察组心功能低下比例高于对照组,差异有统计学意义(P<0.05)。观察组中重度心功能不良的比例高于对照组,差异有统计学意义(P<0.05)。结论心电图上出现fQRS与心肌梗死患者心功能不良关系密切,fQRS对左室收缩功能有直接的影响,出现fQRS的急性心肌梗死患者将会更多地出现中重度左心功能不良,临床可以将其作为评估患者远期预后的一个要素。
Objective To investigate the relationship between fragmented QRS complex(fQRS)and cardiac function in patients with myocardial infarction.Methods A total of 63 inpatients with acute myocardial infarction in Wuxi Huishan District People′s Hospital from January 2017 to January 2020 were selected as the research objects.Electrocardiography(ECG)screening was performed.According to the ECG results,they were divided into the observation group(with fQRS,28 cases)and the control group(non fQRS,35 cases).Cardiac function test related data were compared between the two groups,and the relationship between the presence or absence of fQRS and cardiac function of patients with myocardial infarction was analyzed,and the effect of the presence of fQRS on left ventricular systolic function of patients was assessed.Results The left ventricular ejection fraction(LVEF)values in the observation group were lower than those in the control group,the differences were statistically significant(P<0.05).The observation group had a higher proportion of people with depressed cardiac function than the control group,the difference was statistically significant(P<0.05).The proportion of moderate to severe cardiac dysfunction in the observation group was higher than that in the control group,the difference was statistically significant(P<0.05).Conclusion The appearance of fQRS on ECG is closely related to cardiac dysfunction in patients with myocardial infarction,fQRS has a direct effect on left ventricular systolic function,and patients with acute myocardial infarction presenting with fQRS will have more likely to have moderate to severe left ventricular systolic function,which can be clinically used as an element for evaluating the long-term prognosis of patients.
