【 摘 要 】

Background The presence of notched R or S waves without accompanying typical bundle branch blocks, or the existence of an additional wave like RSR’ pattern in the original QRS complex (with a duration of 120 points (OR = 4.765), age >70 years (OR = 4.041), anterior MI localization (OR = 3.148), and presence of fQRS (OR = 2.484) were significant predictors of primary end points. fQRS increased the predictive ability of GRACE score >120 about two folds (OR = 7.305, P < 0.001). Conclusion Persistent fQRS on ECG is associated with poor prognosis and there is a lack of expected mortality benefit of RPT, particularly that of fibrinolytic therapy, in STEMI patients with fQRS.
