Abstract：Objective By analyzing the incidence of ventricular arrhythmias in patients with old myocardial infarction (OMI) in different parts complicating fragmented QRS complex(fQRS), to explore the relationship between parts of infarction in OMI patients and arrhythmias. MethodsOne hundred and fortyseven OMI patients with fQRS and ventricular arrhythmia were divided into anterior infarction group(group A), inferior infarction group(group B) and lateral wall infarction group(group C) by ECG and colored Doppler characteristics. All of the enrolled cases underwent 24hour Holter inspections and their results about ventricular arrhythmias were separately made comparative analysis. ResultsComparing between group A and group B, the differences of incidences of nonsustained ventricular tachycardia and PVCs Lown grade 3 to 5 were statistically significant (P<0.05). Comparing between group A and group C, the incidence of total number of PVCs<720/24 h was statistically significantly different(P<0.05). There was no statistically significant difference between group B and group C. ConclusionAmong the OMI patients complicated by fQRS and ventricular arrhythmias, the usual type of ventricular arrhythmia differs with the parts of infarction, which increases the diagnostic sensitivity of fQRS for OMI further so as to make early intervention and reduce the incidence of sudden cardiac death.
