Association between initial QRS duration and no-reflow phenomenon in patients with acute left main coronary artery obstruction

      The 12-lead electrocardiogram (ECG) on admission is the established first step to define acute myocardial infarction (AMI), and it provides information to predict outcomes in patients with ST-segment elevation AMI.
