摘要

Aims Dispersion of repolarization (DOR) in the human heart is minimized by activation–repolarization coupling. Adrenergic stimulation can be proarrhythmic in patients with impaired left-ventricular function and its effect on repolarization dispersion has not been systematically investigated. Our objective was to study the effect of dobutamine on repolarization dispersion and activation–repolarization coupling in patients with cardiomyopathy.
