Abstract
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.
