title: Influence of contrast media osmolality on isolated rabbit heart performance.
abstract: A low osmolality contrast medium (Iopamidol) caused less cardiac disturbance on isolated rabbit heart than a high osmolality medium (Urografin). The same effects were induced by glucose solutions iso-osmolal with the two media. After perfusion with Propranolol (1 microgram/ml) and Cimetidine (1 microgram/ml) the observed effect was unaltered.
