Analysis of the electrophysiologic effects of short-term oxybutynin on guinea pig and rabbit ventricular cells.

abstract：:Previous studies in which an isolated heart or in situ constant pressure preparation was used suggested a minimal role for adenosine in autoregulatory control of coronary circulation. These results, however, are controversial, and the role of adenosine in autoregulation of flow in heart is uncertain. To test the hypot...
