摘　　要：目的:探讨急性心肌梗死患者体表心电图碎裂QRS波(fQRS)的出现情况及与冠状动脉病变的关系。方法:回顾性收集2020年2月—2023年2月上海交通大学医学院苏州九龙医院收治的195例急性心肌梗死患者资料,根据患者入院12导联体表定位心电图上是否有fQRS分为有fQRS组(94例)和无fQRS组(101例)。所有患者均行冠状动脉造影术,评估冠脉病变情况,分析fQRS导联出现位置及有fQRS组fQRS导联位置出现情况。结果:有fQRS组单支病变率低于无fQRS组,多支病变率高于无fQRS组,差异有统计学意义(P<0.05);两组双支病变率比较,差异无统计学意义(P>0.05)。两组左前降支、左旋回支和右冠状动脉fQRS导联出现率比较,差异无统计学意义(P>0.05)。有fQRS组下壁导联出现率高于侧壁和上壁导联,差异有统计学意义(P<0.05)。结论:急性心肌梗死患者心电图上fQRS的出现可能提示更大范围的冠状动脉病变,且下壁导联中fQRS出现率更高。Objective:To investigate the occurrence of fragmented QRS waves(fQRS)on the surface electrocardiogram in patients with acute myocardial infarction and its relationship with coronary artery disease.Method:The data of 195 patients with acute myocardial infarction who admitted to Suzhou Kowloon Hospital Shanghai Jiao Tong University School of Medicine from February 2020 to February 2023 were retrospectively collected,the patients were divided into the fQRS group(94 cases)and the non-fQRS group(101 cases)according to the presence or absence of fQRS on the 12-lead surface electrocardiogram.Coronary angiography was performed on all patients to evaluate the condition of coronary artery lesions,and to analyze the location of fQRS leads and the location of fQRS leads in the fQRS group.Result:The single-vessel disease rate in the fQRS group was lower than that in the non-fQRS group,and the multi-vessel disease rate was higher than that in the non-fQRS group(P<0.05);there was no significant difference in the rate of double-vessel disease between two groups(P<0.05).There were no significant differences in the fQRS lead occurrence rate of left anterior descending branch,left circumflex branch and right coronary artery between two groups(P>0.05).The incidence of inferior leads in the fQRS group was higher than those of lateral and superior leads,and the difference was statistically significant(P<0.05).Conclusion:The presence of fQRS on the electrocardiogram of patients with acute myocardial infarction may indicate a more extensive coronary artery lesion,and the incidence of fQRS waves is higher in inferior lead.
