Cw. Buffington et al., REGIONAL OXYGEN-CONSUMPTION PERSISTS IN DYSKINETIC CANINE MYOCARDIUM, Journal of cardiovascular pharmacology, 24(1), 1994, pp. 37-44
Regional myocardial O-2 consumption was measured in anesthetized dogs
both in baseline conditions and during intracoronary infusion of lidoc
aine, verapamil, sodium citrate, or 2,3-butanedione-monoxime (BDM). De
spite regional hypokinesis and dyskinesis during drug infusion, region
al O-2 consumption was reduced only 30-40% by lidocaine, verapamil, an
d citrate and not at all by BDM. These results cast doubt on an import
ant assumption of the ''hibernation'' theory: the protective matching
of regional perfusion and contraction.
