Abstract：Objective To investigate the prognostic value of fragment QRS (fQRS) wave on patient with old myocardial infarction. Methods 143 patients with old myocardial infarction from January 2014 to March 2015 in People′s Hospital of Xinjiang Uygur Autonomous Region were subjected to ECG examination. According to fQRS fragment occurrence, all the patients were divided into four groups: without of pathologic Q wave and fQRS wave group (group A), with only pathologic Q wave group (group B), with only fQRS wave group (group C), with both pathologic Q wave and fQRS wave group (Group D). The incidence rate of ventricular arrhythmias and major cardiovascular events were compared among four groups. Results The incidence rates of grade Ⅲ, ⅣA and ⅣB ventricular arrhythmia in group C and group D were higher than those in group A and group B, the differences were statistically significant (P < 0.05). There was no significant difference between group C and group D (P ＞ 0.05). The incidence rates of major cardiovascular events in group C and group D were significantly higher than those in group A and group B, the differences were statistically significant (P < 0.05). There was no significant difference between group C and group D (P ＞ 0.05). Conclusion fQRS wave closely related with ventricular arrhythmia occurrence，it can be effective in prognosis of independent cardiac events of patients with old myocardial infarction, and can be an independent predictor of mortality.
