Abstract:
ObjectiveThe purpose of this study was to determine whether fQRS is associated with increased ventricular arrhythmic event in patients with Acute ST- elevation Myocardial Infarction.Methods 12-lead ECG, 24h-Holter monitoring and biochemical markers detection were performed in sixty cases with acute ST-elevation myocardial infarction, which were divided into two groups[fQRS group and nonfQRS group]according to Fragmented QRS (fQRS) on 12-lead ECG.Then ventricular arrhythmic events were analyzed.ResultsVentricular premature beats (24 h, 3140 +555 vs 1226 + 142, P ＜0.01) and the incidence of complex ventricular arrhythmic events(34.4％ vs 10.7％, P ＜0.05) in fQRS group were significantly higher than that in non- fQRS group.ConclusionsFragmented QRS may be used to predict ventricular arrhythmic events in patients with acute ST- elevation myocardial infarction.
