title: Predictors of rapid QRS widening in patients with coronary artery disease and left ventricular dysfunction.
abstract: To assess the predictors of rapid QRS widening in patients with chronic ischemic left ventricular dysfunction, 82 patients who underwent > or =2 electrocardiograms and exercise Doppler echocardiography were studied. In a multivariate analysis, left ventricular end-diastolic volume, a large increase in mitral regurgitant volume during exercise, and diabetes emerged as independent predictors of QRS widening.
