Dual effect of disopyramide on atrial and atrioventricular conduction and refractory periods.

PMCID: PMC483295  PMID: 884018

Abstract

Disopyramide has been shown in conditions of cholinergic blockade to have a depressant effect upon sinus node automaticity and the atrial refractoriness. It also prolongs atrioventricular conduction and increases atrioventricular refractoriness. These effects may often be masked in vivo by the anticholinergic effects of the drug.
