Relationship Between QRS Duration on ECG and LV Systolic Function by Echocardiography in Patients with STEMI

Background: Acute STEMI patients constitute a large proportion of admissions in coronary care unit and their management and prognostic implification is of immense importance. Prolonged QRS duration on electrocardiogram (ECG) has been associated with cardiac structural and functional abnormalitiesVery few studies were performed correlating QRS duration and LV systolic function in acute STEMI patients in our country. This study assessed whether QRS duration on ECG is correlated with LV systolic function measured in patients with acute STEMI
