title: Bradycardia and hypotension following use of intravenous contrast media.
abstract: Eight patients had unusual reactions, including hypotension and bradycardia, to intravenous contrast media. These reactions appear to be vagal- or acetylcholine-mediated. Atropine treatment produced prompt reversal in several of the cases, and is felt to be the drug of choice for this particular type of idiosyncratic reaction.
