Abstract :
[en] To assess the predictors of rapid QRS widening in patients with chronic ischemic left ventricular dysfunction, 82 patients who underwent greater than or equal to2 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.
