Fragmented QRS complexes after acute myocardial infarction are independently associated with unfavorable left ventricular remodeling
Recovery of left ventricular ejection fraction (LVEF) after acute myocardial infarction (MI) is not universal and is difficult to predict. Fragmented QRS (fQRS) complexes are thought to be markers of myocardial scar. We hypothesized that fQRS complexes on 12 ‑lead surface ECGs during the initial post-MI period would be associated with adverse LV remodeling over the following year.
