Usefulness of QRS duration in the absence of bundle branch block as an early predictor of survival in non-ST elevation acute myocardial infarction

To determine whether an increased QRS duration in the absence of bundle branch block (BBB) on the presenting electrocardiogram of patients with acute myocardial infarction (AMI) is associated with decreased survival, we retrospectively reviewed 781 consecutive patients admitted to the coronary care...

Description
Summary:To determine whether an increased QRS duration in the absence of bundle branch block (BBB) on the presenting electrocardiogram of patients with acute myocardial infarction (AMI) is associated with decreased survival, we retrospectively reviewed 781 consecutive patients admitted to the coronary care unit of our institution with AMI without BBB between 1988 and 1998. In patients with ST elevation AMI (n = 412), the groups with QRS duration ≥100 ms and
