Abstract
We retrospectively examined the electrocardiograms in all of our patients w ith nonischemic dilated cardiomyopathy and normal sinus rhythm before and a fter at least 3 months of metoprolol (n = 12), bucindolol (n = 8), carvedil ol (n = 6), or no beta blocker (n = 9). Both beta(1)-selective and nonselec tive beta-adrenergic blockade reduced QTc dispersion equally in patients wi th dilated cardiomyopathy.
