Relationship between Left Ventricular Ejection Fraction and Number of Fragmented QRS Complex Derivations on Standard 12-Lead Electrocardiogram in Acute ST-Elevated Myocardial Infarction Patients

OP-024 Fragmented QRS (fQRS) developed by intraventricular depolarization and signal conduction disturbance due to myocardial ischemia, scar or fibrosis. In the literature, some of the studies showed negative correlation between left ventricular ejection fraction (LVEF) and fQRS. Current study,
