Abstract：Objective To explore the clinical value of fragmented QRS complex in diagnosis of acute myocardial infarction (AMI). Methods One hundred and sixtytwo patients with AMI were enrolled in the study and were divided into two groups, fQRS and non-fQRS, according to the presence of fQRS. Incidence rates of reoccur angina, arrhythmia, leads of ST-segment elevation, hospital mortality were compared between two groups. Results The incidence rates of reoccur angina, arrhythmia, leads of ST-segment elevation, hospital mortality in fQRS group were significantly higher than those of non-fQRS group (P<0.05). Conclusion The presence of fragmented QRS complex may be involved in the prognosis of patients with myocardial infarction.
