Relationship between Fragmented QRS Waves on Electrocardiogram and Coronary Artery Lesions in Patients with Acute Myocardial Infarction
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.
