THE PRESENCE OF FRAGMENTED QRS COMPLEXES EARLY AFTER ACUTE MYOCARDIAL INFARCTION IS ASSOCIATED WITH SUBSEQUENT LACK OF FAVORABLE LEFT VENTRICULAR REMODELING

Background: Recovery of left ventricular ejection fraction (LVEF) after myocardial infarction (MI) is not universal and is difficult to predict. Fragmented QRS (fQRS) complexes are thought to be a marker of myocardial scar, and are defined as various RSR’ patterns on a 12-lead surface
