ABSTRACT
We retrospectively examined the electrocardiograms in all of our patients with nonischemic dilated cardiomyopathy and normal sinus rhythm before and after at least 3 months of metoprolol (n = 12), bucindolol (n = 8), carvedilol (n = 6), or no beta blocker (n = 9). Both beta1-selective and nonselective beta-adrenergic blockade reduced QTc dispersion equally in patients with dilated cardiomyopathy.
