Comparison of effects of quinidine and dihydroquinidine on canine heart
Abstract
Various cardiac effects of quinidine and dihydroquinidine were tested in isolated dog hearts and in vivo in dogs. No significant differences were found in the negative inotropic, chronotropic, and dromotropic effects. Dihydroquinidine was more potent than quinidine in decreasing coronary arterial pressure.
